Subject [jira] [Commented] (HDFS-2911) Gracefully handle OutOfMemoryErrors
Date Wed, 08 Feb 2012 21:44:59 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2911?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13204026#comment-13204026
] 

Todd Lipcon commented on HDFS-2911:
-----------------------------------

We could simply recommend the following for the java options in order to make OOME fail fast:
-XX:OnOutOfMemoryError="kill -9 %p"

> 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).
