Description

This happens only when using external metastore (with --hiveconf hive.metastore.uris=thrift://localhost:8088 --hiveconf hive.metastore.local=false). Also if I gave a comment in the statement, this exception go away.

Here is the statement:
create index test111 on table hcat_test(name) as 'compact' with deferred rebuild;

Here is the stack:
