[jira] [Created] (IMPALA-14955) Include libhdfs Java stack trace in HDFS error messages

Siyao Meng created IMPALA-14955:
-----------------------------------

             Summary: Include libhdfs Java stack trace in HDFS error messages
                 Key: IMPALA-14955
                 URL: https://issues.apache.org/jira/browse/IMPALA-14955
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
            Reporter: Siyao Meng


When an HDFS/libhdfs operation fails, Impala currently includes libhdfs root cause output in `GetHdfsErrorMsg()`. However, some failures, especially exceptions raised inside filesystem client code, need the full Java stack trace to identify the actual failing path.

This change appends `hdfsGetLastExceptionStackTrace()` to the HDFS error message when libhdfs provides one.
