> This issue seems to be caused by re-using the same dictionary column vector
> while reading consecutive row groups. This looks like one of the corner case
> bug which occurs for a certain distribution of dictionary/plain encoded data
> while we read/populate the underlying bit packed dictionary data into a
> column-vector based data structure.
> Similar issue issue was reported in spark (Ref:
> https://issues.apache.org/jira/browse/SPARK-16334)
