[jira] [Commented] (HIVE-22121) Turning on hive.tez.bucket.pruning produce wrong results

["Gopal V (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-22121?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16908732#comment-16908732 ] 

Gopal V commented on HIVE-22121:
--------------------------------


{code}
'            Map Operator Tree:'
'                TableScan'
'                  alias: test_table'
'                  filterExpr: (col_1 <> 2) (type: boolean)'
'                  buckets included: [] of 4'
{code}

on the explain extended, the SARG generated is 

{code}
leaf-0 = (EQUALS col_1 2), expr = (not leaf-0)
{code}

So the SARG leaf only has

{code}
[(EQUALS col_1 2)]
{code}

and expression tree does not bail out for NOT.
