Subject [jira] [Created] (HDFS-2911) Gracefully handle OutOfMemoryErrors
Date Tue, 07 Feb 2012 21:53:00 GMT
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: 1.0.0, 0.23.0
            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).
