Subject [jira] [Created] (HBASE-15127) NPE in RpcServer$Call.wrapWithSasl()
Date Tue, 19 Jan 2016 02:49:39 GMT
Enis Soztutar created HBASE-15127:
-------------------------------------

             Summary: NPE in RpcServer$Call.wrapWithSasl()
                 Key: HBASE-15127
                 URL: https://issues.apache.org/jira/browse/HBASE-15127
             Project: HBase
          Issue Type: Bug
            Reporter: Enis Soztutar
             Fix For: 2.0.0, 1.3.0


I saw this in a log file, not sure whether it is important to fix or not:

This is 0.98 based code base corresponding to: 
{code}
      synchronized (connection.saslServer) {
        token = connection.saslServer.wrap(responseBytes, 0, responseBytes.length);
      }
{code}

I believe the saslserver was set to null earlier by {{disposeSasl()}} because Connection is
closing.
