What does AceMQ Apache Hadoop support include?

Our Hadoop support covers 24/7 emergency incident response with a 15-minute SLA, root cause analysis on every P1, HDFS and YARN performance tuning, Kerberos and security hardening, CVE and EOL patch advisory, and migration planning off Hadoop when that's the right call. Every ticket reaches a named senior engineer with no tier-1 triage layer.

Do you support end-of-life Cloudera or Hortonworks distributions?

Yes. Many enterprises are stranded on distributions that no longer receive vendor patches after the Cloudera-Hortonworks consolidation. We support these clusters with bug workarounds and backported mitigations, and we'll also give you an honest read on whether a migration is worth planning now versus later.

Can you help us migrate off Hadoop entirely?

Yes, and we start with an honest assessment rather than a sales pitch. We look at your actual workload mix against lakehouse or cloud-native alternatives, and if a Hadoop cluster is fixable and a migration would be expensive theatre, we'll say so. When migration is the right call, we plan and execute it.

What causes NameNode heap exhaustion?

Almost always small-file sprawl. Every file and block in HDFS consumes roughly 150 bytes of NameNode heap regardless of file size, so a cluster accumulating millions of small files eventually runs the NameNode out of memory even though total data volume looks modest. We diagnose and remediate this as a standard part of support.

Do you support Kerberized, secured Hadoop clusters?

Yes. Secure cluster support — ticket lifetime tuning, keytab management, and renewal configuration for long-running jobs — is a core part of our Hadoop support, since most regulated enterprises running Hadoop are running it Kerberized.

How fast do you respond to a Hadoop production outage?

P1 emergencies — NameNode down, a cluster-wide re-replication storm, YARN queues frozen — get a 15-minute first response with a senior engineer joining a live bridge. P2 critical issues are 1 hour, P3 high-priority 4 hours, and P4 standard questions next business day. These are contractual targets.

How is AceMQ Apache Hadoop support priced?

Support is priced as an annual contract based on your cluster size, required SLA tier, and coverage hours — not per incident or per ticket. Contact us for a quote; we turn them around within 24 hours.

Escalation Path

Your first hour of a Apache Hadoop outage

Most vendors publish an SLA number. This is what actually happens, minute by minute, when you page a senior AceMQ engineer.

T+0

You page us

Phone, email, or Slack — any channel reaches the on-call senior engineer directly. No web form, no tier-1 queue.

T+15

Named engineer live

A senior engineer who already knows your environment joins a live bridge. Zero cold-start, no re-explaining your topology.

T+30

Root cause isolated

Direct broker access, log and metric review, and a working hypothesis with a rollback plan before we touch anything.

Post

Written RCA

Documented root cause, the fix applied, and the prevention steps — delivered after every P1, not just when asked.

Response Times

SLA tiers, contractually guaranteed

Every tier reaches a senior Apache Hadoop engineer. There is no tier-1 triage layer to get through.

P1 — Emergency

15 min

Production down, messages not flowing, cluster or broker failure

P2 — Critical

1 hour

Severe degradation, rising error rates, approaching capacity limits

P3 — High

Incident Triage

Apache Hadoop problems we fix every week

These are real symptoms from real Apache Hadoop production environments — and the first thing our engineers check when one comes in.

Symptom you're seeingWhat we check firstTypical resolution

NameNode heap climbing steadily toward OOM

What we check firstSmall-file count via `hdfs dfsadmin -report` and fsimage size. Every file and block consumes roughly 150 bytes of NameNode heap, and small-file sprawl is the classic HDFS heap killer.

Typical resolution1–3 hours

Cluster stuck in a re-replication storm after disk failures

What we check firstDataNode disk health and under-replicated block count. A failed disk on a densely packed DataNode can trigger cluster-wide re-replication that saturates network bandwidth for hours.

Typical resolution2–4 hours

YARN jobs stuck pending despite idle capacity elsewhere

What we check firstFair or capacity scheduler queue configuration. A queue with a low max-capacity cap starves jobs even when the cluster overall has plenty of free resources.

Typical resolution1–2 hours

NameNode HA failover doesn't complete cleanly

What we check firstZKFC logs and fencing method configuration. A failed fencing script leaves the old active NameNode in an ambiguous state with both NameNodes contending for the role.

Typical resolution2–4 hours

Cluster-wide slowdown right after a large restart

What we check firstBlock report timing across DataNodes for a block report storm — every DataNode reporting its full block inventory to the NameNode simultaneously overwhelms it after a coordinated restart.

Typical resolution1–3 hours

Jobs fail mid-run with authentication errors on a secured cluster

What we check firstKerberos ticket TTL against actual job runtime. Long-running jobs outlive the default ticket lifetime when renewal isn't configured.

Typical resolutionUnder 2 hours

Running an end-of-life Cloudera or Hortonworks distribution

What we check firstCurrent CVE exposure and available upgrade or migration paths. Vendor consolidation left many clusters stranded on releases that no longer receive patches.

Typical resolutionSame day

Evaluating whether to modernize off Hadoop entirely

What we check firstCurrent workload mix — batch ETL, ML, or ad hoc query — against lakehouse and cloud-native alternatives. The case for migration is usually falling further behind on patches, not raw performance.

Typical resolutionSame day

Resolution times reflect typical Apache Hadoop engagements under an active AceMQ support contract. Every P1 closes with a written root-cause analysis.

What's Included

Everything in your Apache Hadoop support contract

No add-on pricing for incidents. No per-ticket charges. One contract covers the whole surface.

Emergency Incident Response

NameNode down, a re-replication storm saturating the network, or YARN queues frozen. A senior engineer joins a live bridge within 15 minutes.

Root Cause Analysis

Every P1 closes with a written RCA: what failed, why, the fix applied, and the configuration change that prevents recurrence.

HDFS & YARN Performance Tuning

Scheduler queue configuration, NameNode heap and small-file remediation, and block placement policy tuned against your actual cluster shape.

Security & Kerberos Hardening

Ticket lifetime and renewal configuration, keytab management, and secure cluster hardening for regulated environments that can't run unsecured.

CVE & EOL Patch Advisory

Proactive advisory for clusters running end-of-life Cloudera or Hortonworks distributions, including backported mitigations where official fixes no longer exist.

Migration Off Hadoop

Honest assessment of whether to modernize onto a lakehouse or cloud-native platform, and execution of that migration when it's the right call — not a sales pitch either way.

Anywhere You Run It

We support Apache Hadoop wherever it's deployed

Cloud, Kubernetes, bare metal, hybrid, and air-gapped — including environments where you can't give us outbound network access.

Why AceMQ

What you get that you don't get elsewhere

Named Engineers Who Still Know Hadoop Internals

Classic Hadoop expertise is scarce and getting scarcer. The same senior engineers stay on your account and actually know HDFS block placement and YARN scheduler internals, not just how to run kubectl against something newer.

No Tier-1 Triage Layer

You reach a senior Hadoop engineer directly by phone, email, or Slack. No help desk, no escalation approval process standing between you and a fix.

Honest Exit-Path Guidance

We support both keeping Hadoop running and planning a migration off it — and we'll tell you plainly which one actually makes sense for your workload instead of defaulting to whichever we happen to sell.

EOL Distribution Support

We support Hadoop clusters running distributions that no longer receive vendor patches, including bug workarounds and backported mitigations for regulated environments that can't upgrade on the community's timeline.

Genuine Follow-the-Sun Coverage

Engineers across 26+ countries and every time zone. Your 3am NameNode failover is someone's mid-afternoon — no overnight skeleton crew.

Full-Stack, Not Just HDFS

Hadoop problems are frequently OS, network, or disk problems wearing an HDFS error message. We diagnose across the whole stack, including the hardware layer where legacy clusters often show their age.
