Dongjoon Hyun resolved SPARK-31265.
-----------------------------------
Resolution: Invalid
> Add -XX:MaxDirectMemorySize jvm options in yarn mode
> ----------------------------------------------------
>
> Key: SPARK-31265
> URL: https://issues.apache.org/jira/browse/SPARK-31265
> Project: Spark
> Issue Type: Improvement
> Components: YARN
> Affects Versions: 3.0.0
> Reporter: wangzhun
> Priority: Minor
>
> Current memory composition `amMemory` + `amMemoryOverhead`
> {code:java}
> val capability = Records.newRecord(classOf[Resource])
> capability.setMemory(amMemory + amMemoryOverhead)
> capability.setVirtualCores(amCores)
> if (amResources.nonEmpty) {
> ResourceRequestHelper.setResourceRequests(amResources, capability)
> }
> logDebug(s"Created resource capability for AM request: $capability")
> {code}
> {code:java}
> // Add Xmx for AM memory
> javaOpts += "-Xmx" + amMemory + "m"
> {code}
> It is possible that the physical memory of the container exceeds the limit
> and is killed by yarn.
> I suggest setting `-XX:MaxDirectMemorySize` here
> {code:java}
> // Add Xmx for AM memory
> javaOpts += "-Xmx" + amMemory + "m"
> javaOpts += s"-XX:MaxDirectMemorySize=${amMemoryOverhead}m"{code}
