Description
According to the Apache Tez code, parameter `tez.grouping.max-size` is supported.
https://github.com/apache/tez/blob/1e6c9e3448bb9d934508ee995ad60c23dafa0610/tez-mapreduce/src/main/java/org/apache/tez/mapreduce/grouper/TezSplitGrouper.java#L72
Also when hive uses tez engine, it is possible to set the `tez.grouping.max-size` parameter, but the current version fail to parse it.

Research direction
Start by reproducing the Hive statement `set tez.grouping.max-size=1234;` and inspect the Hive dialect parsing path. Use the Apache Tez reference in the issue to confirm the parameter is supported; done means the statement parses successfully without regressing existing Hive syntax.
