Review comment:
Yes, It will be preserved. The entire stack trace is written here.
https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/exec/repl/util/ReplUtils.java#L353
and the exception is already set above, example:
https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/exec/repl/ReplLoadTask.java#L141
Every code that calls this sets the exception before and calls this for
error code to check if it is recoverable or non-recoverable.
This logic is just to get the error code, which is used to decide whether
the error is recoverable or non-recoverable.
And the trace is also propagated back, example from `testFailureScenarios()`:
```
Caused by: org.apache.hadoop.hdfs.protocol.SnapshotException: Nested
snapshottable directories not allowed:
path=/testFailureScenariossource1/tablesource, the ancestor
/testFailureScenariossource1 is already a snapshottable directory.
