Description

when create a table CarbonCreateTableCommand will do twice catalog check, one is under CarbonCreateTableCommand file another is under CreateDataSourceTableCommand.

CreateDataSourceTableCommand may throw AnalysisException and CarbonCreateTableCommand  will catch it. 

if we have 2 command create the same table, something bad will happen.

 

create table A  1

      A carbon check pass 1

create table A 2

     A carbon check pass 2

     A sparksql check pass 2

     A sparksql check no pass 1

     throw AnalysisException  1

     delete table A folder    1

In this case, the following table A will be deleted.

if the create table use the location then the location will be delete.
