> 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: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}
