> It is observed that RM crashes with heap space OOM in secure cluster(http
> authentication is kerborse) when RM HA is enabled.
> Scenario is
> 1. Start RM in HA secure mode. Lets say RM1 is active mode.
> 2. Run many applications so that it uses greater than 50% of heap space
> configured. Lets say, if heap space is 2GB, then run applications that occupy
> 1.5GB of heap space.
> 3. Switch RM to StandBy and bring back to Active! While recovering
> applications from state store, RM crashes with OOM.
> *Note* : This issue will happen only when RM is started as ACTIVE directly.
> (not switched from standby to active during start of JVM)
> Heap dump shows that RMAuthenticationFilter holds 60% heap space! And other
> 40% held by RMAppState which is during recovering from state store. This
> exceeds the heap space and crashes with OOM.
