Subject [jira] [Commented] (HIVE-12950) get rid of the NullScan emptyFile madness (part 1 - at least for Tez and LLAP)
Date Wed, 03 Feb 2016 23:09:39 GMT

    [ https://issues.apache.org/jira/browse/HIVE-12950?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15131337#comment-15131337
] 

Matt McCline commented on HIVE-12950:
-------------------------------------

I see that OneNullRowInputFormat now has the marker interface VectorizedInputFormatInterface
so the Vectorizer class will recognize it.

And, NullRowsInputFormat has new method makeNullVrb.

Does the vectorized row batch created by VectorizedRowBatchCtx.createVectorizedRowBatch have
null columns for those column not in columnsToIncludeTruncated?  Should that be a Preconditions.checkState
in the for loop in makeNullVrb?
