Subject [jira] [Created] (HBASE-7684) NullPointerException in SecureClient when Call is cleaned up due to RPC timeout

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

             Summary: NullPointerException in SecureClient when Call is cleaned up due to
RPC  timeout
                 Key: HBASE-7684
                 URL: https://issues.apache.org/jira/browse/HBASE-7684
             Project: HBase
          Issue Type: Bug
          Components: security
    Affects Versions: 0.94.3
            Reporter: cuijianwei


We find NullPointException when using SecureClient to access hbase. From the source code,
we find that receiveResponse() will not check call != null before invoke call.setValue(...)(line
378 and 380 in SecureClient.java). However, as explained in receiveResponse() of HBaseClient,
the call may have been cleaned up due to RPC timeout; therefore, it should be better to check
call != null before invoke call.setValue(...) in SecureClient
