Apache Spark Support

24/7 Apache Spark Support with a 15-Minute Emergency SLA

AceMQ supports Apache Spark in production across Databricks, EMR, Dataproc, and Kubernetes — executor OOM from partition skew, shuffle spill tanking runtime, and driver crashes from an unbounded collect(). Every ticket reaches a named senior engineer who reads Spark UI stage detail live.

Escalation Path

Your first hour of a Apache Spark 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 Spark 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
4 hours

Performance issues, configuration problems, non-critical failures

P4 — Standard
Next day

Questions, guidance, best practices, non-urgent improvements

Incident Triage

Apache Spark problems we fix every week

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

Executors OOM mid-job with no code change
What we check firstSpark UI stage detail for partition size skew, and whether a broadcast join is broadcasting a table larger than spark.sql.autoBroadcastJoinThreshold.
Typical resolutionUnder 2 hours
Job runtime doubles, heavy shuffle spill to disk
What we check firstShuffle read/write metrics in stage detail against executor memory fraction. Insufficient shuffle buffer relative to partition count forces spill that looks like a network problem but isn't.
Typical resolution1–3 hours
Output stage writes thousands of tiny files
What we check firstOutput partition count against actual data volume — usually a missing coalesce or repartition before write, or overly granular partitionBy columns.
Typical resolution1–2 hours
Driver crashes with 'ran out of memory'
What we check firstJob code for collect() or toPandas() calls on a dataset that grew past what fits in driver memory since the job was last tuned.
Typical resolutionUnder 2 hours
Dynamic allocation won't scale executors under load
What we check firstspark.dynamicAllocation.maxExecutors against cluster resource manager queue caps — a scheduler queue limit often silently caps scale-out below the configured Spark max.
Typical resolution1–3 hours
Stages retry repeatedly on a specific node pool
What we check firstCluster manager logs for spot or preemptible instance reclamation events. Fetch failures cascade when shuffle data lived only on nodes that just got reclaimed.
Typical resolution2–4 hours
One task runs for hours while its stage siblings finish in minutes
What we check firstPartition key cardinality for skew. Salting the join key, or enabling adaptive query execution's skew join handling, is the standard fix.
Typical resolution1–3 hours
A job behaves differently in local dev than on the cluster
What we check firstSpark config diff between spark-defaults.conf and SparkSession builder overrides, plus Scala/Python/JAR version mismatches between environments.
Typical resolutionSame day

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

What's Included

Everything in your Apache Spark support contract

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

Emergency Incident Response

Jobs failing cluster-wide, an executor OOM loop, or a pipeline that stopped producing output. 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.

Performance Tuning

Partitioning strategy, shuffle configuration, and memory sizing tuned against your actual data volumes and skew profile — not generic Spark config defaults.

Pipeline Architecture Review

Job design review to catch skewed joins, unbounded collect() calls, and small-file output patterns before they become a 2am page.

Cluster Sizing & Cost Optimization

Executor sizing and dynamic allocation configuration matched against actual job resource needs, so you're not paying for headroom you never use.

Migration & Upgrade Support

Spark version upgrades with compatibility testing, and migration off legacy Hadoop-based Spark deployments onto modern cloud-native platforms.

Anywhere You Run It

We support Apache Spark 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, Zero Cold Start

The same senior engineers stay on your account. They know your job topology and where your skew lives — so a P1 starts with the Spark UI, not you re-explaining your pipeline.

No Tier-1 Triage Layer

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

Batch and Streaming, Both Deeply

We support Spark alongside Flink, which means we think in the same terms for batch and streaming compute rather than treating them as unrelated disciplines.

Hadoop-to-Modern Migration Expertise

Many Spark clusters still run on legacy Hadoop infrastructure. We support both, so a migration off Hadoop onto cloud-native Spark is planned by people who've done the move, not just the destination.

Genuine Follow-the-Sun Coverage

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

Full-Stack, Not Just the JVM

Spark problems are frequently cluster manager, cloud storage, or network problems wearing a stack trace. We diagnose across the whole path, not just Spark's own logs.
