https://github.com/apache/carbondata/pull/2743 [CARBONDATA-2953]fixed dataload failure with sort columns and query wrong result from other session
### Problem:
1) when dataload is done with sort columns, it fails with following exeptions
2) when two sessions are running in parallel, the follow below steps in session1
drop table
create table
load data to table
follow below step in session2
query on table(select * from table limit 1), then the query returns null result instead of proper result
### Solution
1) During sorting, the index increament for no dictionary measure data was not happening correctly, hence was trying to cast to byte array and failing
2) If table is dropped from first session and created again, and queries from another session, the metastore needs to be updated for newly created table, but since the database in identifier was None. we were trying to get old table from default database, here need to get from current database
