    @rajrahul, thanks for submitting the patch. It looks good. I guess we missed dictionary
encoded int96 timestamps (even though timestamps with nanosecond precision) are the one thing
that should never, ever, be dictionary encoded!
    
    Just to make sure, I tried the use the sample file in DRILL-6016, but I could not even
unzip it! Can you please check and see if the file is correct? WE can use that to create the
unit test as well.

> Hi,
> I am getting the error - SYSTEM ERROR : ClassCastException: org.apache.drill.exec.vector.TimeStampVector
cannot be cast to org.apache.drill.exec.vector.VariableWidthVector while trying to read a
spark INT96 datetime field on Drill 1.11 in spite of setting the property store.parquet.reader.int96_as_timestamp
to  true.
> I believe this was fixed in drill 1.10(https://issues.apache.org/jira/browse/DRILL-4373).
What could be wrong.
> I have attached the dataset at https://github.com/rajrahul/files/blob/master/result.tar.gz
