Subject [jira] [Updated] (DRILL-6203) Repeated Map Vector does not give correct payload bytecount
Date Tue, 06 Mar 2018 23:55:00 GMT

     [ https://issues.apache.org/jira/browse/DRILL-6203?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Padma Penumarthy updated DRILL-6203:
------------------------------------
    Description: 
Repeated Map Vector does not give correct payload byte count. It calls abstractMapVector method
which gives payload byte count for a given value count for simple map (non repetitive) case.
We need to overload this method for repeated map to get the right numbers. 

Also, Repeated Map and Repeated List vectors implement RepeatedFixedWidthVectorLike and that
causes problems when doing memory allocation with AllocationHelper routines for those vectors. 

  was:Repeated Map Vector does not give correct payload byte count. It calls abstractMapVector

case. We need to overload this method for repeated map to get the right numbers.
