   This exception is throwed by create table command by chance， not every time.
   I think the reason is  type of carbonTables in MetaData.class is ArrayBuffer, and the ArrayBuffer is not thread-safe and we drop tables and create tables at the same time in a carbon session
   Do you have other ideas?
