[jira] [Commented] (KYLIN-742) Route unsupported queries to SparkSQL

    [ https://issues.apache.org/jira/browse/KYLIN-742?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14595317#comment-14595317 ] 

Aroop Maliakkal commented on KYLIN-742:
---------------------------------------

Why can't we use hive-on-spark instead of SparkSQL ? In this way, the change will be relatively minimum given that we already have code for sending queries to hive and we have turned it off due to performance issues.

Thoughts ?

> When Kylin can't serve coming SQL, it will be better to route it to enabled SQL on Hadoop like SparkSQL and execute there. 
> Then get result and return to client through Kylin server.
