When we take a > heap dump at a standby, the NN still accepts the socket connection but it > won't send responses to these RPC requests and we would timeout after > _ipc.client.rpc-timeout.ms._ This adds a significantly latency. For clusters > at Linkedin, we set _ipc.client.rpc-timeout.ms_ to 120 seconds and thus a > request takes more than 2 mins to complete when we take a heap dump at a > standby. This has been causing user job failures. > We could set _ipc.client.rpc-timeout.ms to_ a smaller value when sending > getHAServiceState requests in ObserverReaderProxy (for user rpc requests, we > still use the original value from the config). However, that would double the > socket connection between clients and the NN (which is a deal-breaker). > The proposal is to add a timeout on getHAServiceState() calls in > ObserverReaderProxy and we will only wait for the timeout for an NN to > respond its HA state. Once we pass that timeout, we will move on to probe the > next NN. > -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
