[jira] [Closed] (IMPALA-500) implment query hashes and query plan hashes

["Aman Sinha (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/IMPALA-500?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Aman Sinha closed IMPALA-500.
-----------------------------
    Resolution: Won't Fix

We haven't seen a compelling need for creating hash of the query text or the plan and considering this JIRA is quite old, closing this for now. I think that if and when we add plan caching (for parameterized queries to re-use the same plan), it would make sense to revisit something like this.

> Having hashes for the query text and the query execution plan in the log (and other places) would make comparing plans or finding identical queries easier.
