Parth Chandra commented on DRILL-4070:
--------------------------------------
I'm working on putting together a migration tool that will update the created
by string to the current version for files created by older versions of Drill.
That should take care of this problem. I'll post the link to the tool in this
JIRA.

> The metadata cache file created contains incorrect values for min/max fields
> for varchar colums. The data is also partitioned on the varchar column
> {code}
> refresh table metadata fewtypes_varcharpartition;
> {code}
> As a result partition pruning is not happening. This was working after
> DRILL-3937 has been fixed (d331330efd27dbb8922024c4a18c11e76a00016b)
> I attached the data set and the cache file
