[jira] [Commented] (HIVE-6535) JDBC: async wait should happen during fetch for results

["Thejas M Nair (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-6535?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15221207#comment-15221207 ] 

Thejas M Nair commented on HIVE-6535:
-------------------------------------

The setting of isLogBeingGenerated in HiveStatement has to be handled. Looks like it would need to be moved to HiveQueryResultSet. Note that HiveStatement.hasMoreLogs is documented as a public method, so that would still need to be around.

> The hive jdbc client waits query completion during execute() call. It would be better to block in the jdbc for completion when the results are being fetched.
> This way the application using hive jdbc driver can do other tasks while asynchronous query execution is happening, until it needs to fetch the result set.
