-----------------------------------
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.
