["Amareshwari Sriramadasu (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LENS-329?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14352713#comment-14352713 ] 

Amareshwari Sriramadasu commented on LENS-329:
----------------------------------------------

Yes. We should do the changes the same way. But we would still need changes on lens-driver-jdbc with respect how to we accept configuration for driver - https://github.com/apache/incubator-lens/blob/master/lens-driver-jdbc/src/main/java/org/apache/lens/driver/jdbc/JDBCDriverConfConstants.java and https://github.com/apache/incubator-lens/blob/master/lens-driver-jdbc/src/main/resources/jdbcdriver-default.xml - Should be updated with more keys for estimate pool, no?

> If estimate is being called aggressively, do we want use same pool across both execute and estimate in Lens? Shall we separate them for isolation?
