Review Comment:
GetHdfsErrorMsg now appends libhdfs exception stack trace (and previously
also appended the root cause), but the function’s documentation still describes
it as only prefix/file + errno. Please update the API comment (in hdfs-util.h)
so callers know the returned message may include multi-line Java exception
details.

> Include libhdfs Java stack trace in HDFS error messages

> 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.
