Description

I'm not 100% aware of historical reasons, but this single-value enum seems totally useless at the moment.
https://github.com/apache/hive/blob/86a15600ae610e1c6017019883ef9344585572ef/itests/util/src/main/java/org/apache/hadoop/hive/cli/control/AbstractCliConfig.java#L50-L52

According to HIVE-14854, it may have made sense when there was an initiative of hbase metastore, but it's not in the scope anymore AFAIK.
