Sergio Peña commented on HIVE-14005:
------------------------------------
I'm moving this JIRA out of 2.1.1 release as it is not a blocker nor critical
for a 2.1.1 RC version. Feel free to commit it to branch 2.1 if the patch is
ready before the release.
> Changing a string column of ORC table to boolean sets values to be 'NULL'
