[jira] [Created] (HADOOP-12178) NPE during handling of SASL setup if problem with SASL resolver class

Steve Loughran created HADOOP-12178:
---------------------------------------

             Summary: NPE during handling of SASL setup if problem with SASL resolver class
                 Key: HADOOP-12178
                 URL: https://issues.apache.org/jira/browse/HADOOP-12178
             Project: Hadoop Common
          Issue Type: Bug
          Components: ipc
    Affects Versions: 2.7.1
            Reporter: Steve Loughran


If there's any problem in the constructor of {{SaslRpcClient}}, then IPC Client throws an NPE rather than forwarding the stack trace. This is because the exception handler assumes that {{saslRpcClient}} is not null, that the exception is related to the SASL setup itself.

The exception handler needs to check for {{saslRpcClient}} being null, and if so, rethrow the exception
