Subject [jira] [Commented] (HIVE-5441) Async query execution doesn't return resultset status
Date Mon, 21 Oct 2013 21:25:48 GMT

    [ https://issues.apache.org/jira/browse/HIVE-5441?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13801097#comment-13801097

Vaibhav Gumashta commented on HIVE-5441:
----------------------------------------

[~prasadm] Another query: so I'm guessing that after compilation, in the use case you pointed
to, you're planning to use the presence of fetch task in the plan (like here: https://github.com/apache/hive/blob/trunk/service/src/java/org/apache/hive/service/cli/operation/SQLOperation.java#L110)
to determine if it will generate a result set before the query is run, and not set TOperationHandle#hasResultSet
to true?

> For synchronous statement execution (SQL as well as metadata and other), the operation
handle includes a boolean flag indicating whether the statement returns a resultset. In case
of async execution, that's always set to false.
