---------------------------------------
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
