> Currently as part of heartbeat response RM sets all application's tokens though all applications might not be active on the node. On top of it NodeHeartbeatResponsePBImpl converts tokens for each app into SystemCredentialsForAppsProto. Hence for each node and each heartbeat too many SystemCredentialsForAppsProto objects were getting created.
> We hit a OOM while testing for 2000 concurrent apps on 500 nodes cluster with 8GB RAM configured for RM
