Yes. Hive supports parallel transactions. Your error could be generated by a global setting override at session level. If your global tez.grouping_min-size is not low enough to allow you to set your session tez.grouping.max-size to a value higher than the global tez.grouping.min-size, you may want to change the global tez.grouping.min-size to a lower value to satisfy the condition.

This seems to be similar to: https://community.hortonworks.com/questions/50008/while-executing-a-select-sql-on-hive-we-are-seeing...

Let me know if this is different.
