Subject [jira] [Commented] (HIVE-15795) Support Accumulo Index Tables in Hive Accumulo Connector
Date Sat, 22 Apr 2017 18:48:04 GMT

    [ https://issues.apache.org/jira/browse/HIVE-15795?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15980078#comment-15980078
] 

Mike Fagan commented on HIVE-15795:
-----------------------------------

I see the error when processing the following statement:
select * from accumulo_index_test where eff_rating <= 4.5;

The DefaultGraphWalker now it generates a node of :
GenericUDFOPEqualOrLessThan(Column[eff_rating], Const decimal(2,1) 4.5)

previously it used to generate a node of 
GenericUDFOPEqualOrLessThan(Column[eff_rating], Const float 4.5)  (float being the type of
column eff_rating)

is the new behavior expected and desired?
