Subject [jira] [Commented] (HIVE-5230) Better error reporting by async threads in HiveServer2
Date Thu, 26 Sep 2013 12:22:03 GMT

    [ https://issues.apache.org/jira/browse/HIVE-5230?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13778703#comment-13778703
] 

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()?

> [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).
