Brock Noland commented on HIVE-5230:
------------------------------------
This looks good to me, meaning +1. One question, is possible that in
checkExecutionStatus, while we are calling getBackgrounException() that another
thread would call setBackgrounException()?
> Better error reporting by async threads in HiveServer2

> [HIVE-4617|https://issues.apache.org/jira/browse/HIVE-4617] provides support
> for async execution in HS2. When a background thread gets an error, currently
> the client can only poll for the operation state and also the error with its
> stacktrace is logged. However, it will be useful to provide a richer error
> response like thrift API does with TStatus (which is constructed while
> building a Thrift response object).
