No. We did not see any issue with create table (without select). Create table as select also passes sometimes. We are using MySQL for our metastore. Will get back to you on load at the time of create. Is there a direct way to know the load? So, what is the solution/workaround if there is a metastore issue?

Which RDBMS are you using for metastore? MySQL or Oracle? Was your database/thrift server heavy-loaded at that time?
