> Key: SPARK-16332
> URL: https://issues.apache.org/jira/browse/SPARK-16332
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.0.0
> Environment: this is seen on both x86 (Intel(R) Xeon(R), E5-2699 )
> and ppc platform IBM Power8 Habanero (Model: 8348-21C), Red Hat Enterprise
> Linux Server release 7.2 (Maipo), Spark2.0.0-preview (May-24, 2016)
> Reporter: Peter Liu
>
> the JVM instance of the Spark history server of spark2.0-preview (may-24
> build) consumes more than 1000% cpu without the spark standalone cluster (of
> 6 nodes) being under load.
> When under load (1TB input data for a SQL query scenario), the JVM instance
> of the Spark history server of spark2.0-preview consumes 2000% cpu (as seen
> with "top" on linux 3.10)
> Note: can't see a proper Component selection here, surely not a Web GUI issue.
