> Handle vector creation in HbaseRecordReader to avoid NullableInt vectors later
> ------------------------------------------------------------------------------
>
> Key: DRILL-5896
> URL: https://issues.apache.org/jira/browse/DRILL-5896
> Project: Apache Drill
> Issue Type: Bug
> Components: Storage - HBase
> Affects Versions: 1.11.0
> Reporter: Prasad Nagaraj Subramanya
> Assignee: Prasad Nagaraj Subramanya
> Fix For: 1.12.0
>
>
> When a hbase query projects both a column family and a column in the column
> family, the vector for the column is not created in the HbaseRecordReader.
> So, in cases where scan batch is empty we create a NullableInt vector for
> this column. We need to handle column creation in the reader.
