Subject [jira] [Created] (HBASE-13454) SecureClient#setupIOStreams should handle all Exception
Date Sat, 11 Apr 2015 08:38:12 GMT
cuijianwei created HBASE-13454:
----------------------------------

             Summary: SecureClient#setupIOStreams should handle all Exception
                 Key: HBASE-13454
                 URL: https://issues.apache.org/jira/browse/HBASE-13454
             Project: HBase
          Issue Type: Bug
          Components: Client, security
    Affects Versions: 0.94.27
            Reporter: cuijianwei


Similar to [#HBASE-9256], SecureClient#setupIOStreams should also catch up all Exception.
In our production environment, an OutOfMemoryError is thrown in SecureClient#setupIOStreams,
leaving an unclosed SecureConnection with its inputStream/outputStream still null. Therefore,
following calls will be attached to this connection and will encounter NPE in HBaseClient#sendParam:
{code}
java.lang.NullPointerException
at org.apache.hadoop.hbase.ipc.HBaseClient$Connection.sendParam(HBaseClient.java:619)
at org.apache.hadoop.hbase.ipc.HBaseClient.call(HBaseClient.java:977)
at org.apache.hadoop.hbase.ipc.SecureRpcEngine$Invoker.invoke(SecureRpcEngine.java:107)
at $Proxy21.replicateLogEntries(Unknown Source)
at org.apache.hadoop.hbase.replication.regionserver.ReplicationSource.shipEdits(ReplicationSource.java:772)
at org.apache.hadoop.hbase.replication.regionserver.ReplicationSource.run(ReplicationSource.java:451)
{code}
We'd fix this in 0.94.
