Tsz Wo (Nicholas), SZE commented on HDFS-2911: ---------------------------------------------- Sure, logging a message and then calling System.exit(..) probably are doable. I doubt if we can have anything more than that. > Gracefully handle OutOfMemoryErrors > ----------------------------------- > > Key: HDFS-2911 > URL: https://issues.apache.org/jira/browse/HDFS-2911 > Project: Hadoop HDFS > Issue Type: Improvement > Components: data-node, name-node > Affects Versions: 0.23.0, 1.0.0 > Reporter: Eli Collins > > We should gracefully handle j.l.OutOfMemoryError exceptions in the NN or DN. > We should catch them in a high-level handler, cleanly fail the RPC (vs > sending back the OOM stackrace) or background thread, and shutdown the NN or > DN. Currently the process is left in a not well-test tested state > (continuously fails RPCs and internal threads, may or may not recover and > doesn't shutdown gracefully). -- This message is automatically generated by JIRA.
