Not a definitive answer, but my test result might help. I tested with HiveServer2 1.2.2 and Metastore 2.3.6. Queries in the TPC-DS benchmark (which only read data and never update) run okay. Creating new tables and loading data to tables also work okay. So, I guess for basic uses of Hive, running HiveServer2 1.2 against Metastore 2.3 should be fine.
What I am not sure about is whether queries involving transactions work okay when HiveServer2 1.2 connects to Metastore 2.3. Please note that I have not tested with Hive 1.1. Perhaps those familiar with internals of Metastore in this mailing list could give more accurate answers. As a side note, HiveServer2 2.3 can connect to Metastore 3.1. However, HiveServer2 1.2 seems to have a problem with connecting to Metastore 3.1.
