[jira] [Commented] (SPARK-19814) Spark History Server Out Of Memory
/ Extreme GC
[ https://issues.apache.org/jira/browse/SPARK-19814?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15894942#comment-15894942 ]
Sean Owen commented on SPARK-19814:
-----------------------------------
I'm not sure if this is a bug. It depends on how much memory you give, how much data the history server stores. 4G may not be enough; increase that?
Unless it's a memory leak or some obviously too large data structure, I don't think it's a bug, but if you have a concrete optimization, you can open a pull request.

>
> Key: SPARK-19814
> URL: https://issues.apache.org/jira/browse/SPARK-19814
> Project: Spark
> Issue Type: Bug
> Components: Web UI
> Affects Versions: 1.6.1, 2.0.0, 2.1.0
> Environment: Spark History Server (we've run it on several different Hadoop distributions)
> Reporter: Simon King
> Attachments: SparkHistoryCPUandRAM.png

> Spark History Server runs out of memory, gets into GC thrash and eventually becomes unresponsive. This seems to happen more quickly with heavy use of the REST API. We've seen this with several versions of Spark.
> Running with the following settings (spark 2.1):
> spark.history.fs.cleaner.enabled true
> spark.history.fs.cleaner.interval 1d
> spark.history.fs.cleaner.maxAge 7d
> spark.history.retainedApplications 500
> We will eventually get errors like:
> 17/02/25 05:02:19 WARN ServletHandler:ยท

> In our case we see memory usage gradually increase over perhaps 2 days, then level off near max heap size (4G in our case), then often within 12-24 hours GC activity will start to increase, and will result in more and more frequent errors, as in the stack trace above.
