> Issue Type: Improvement
> Components: Metastore
> Affects Versions: 3.0.0
> Reporter: Naveen Gangam

> CREATE INDEX PCS_STATS_IDX ON PAR T_COL_STATS
> (DB_NAME,TABLE_NAME,COLUMN_NAME,PARTITION_NAME)
> Error: ORA-01450: maximum key length (6398) exceeded (state=72000,code=1450)
> Customer tried the same DDL in SQLDevloper, and got the same error. This
> could be a result of combination of DB level settings like the db_block_size,
> limiting the maximum key length, as per below doc:
> http://www.dba-oracle.com/t_ora_01450_maximum_key_length_exceeded.htm
> Also {{NLS_LENGTH_SEMANTICS}} is by default BYTE, but users can set this at
> the session level to CHAR, thus reducing the max size of the index length. We
> have increased the size of the COLUMN_NAME from 128 to 767 (used to be at
> 1000) and TABLE_NAME from 128 to 256. This by setting
> {code}
