> Hive partitioned table's column stats are stored on partition level which is in PART_COL_STATS in sys.
> When "column stats <table_name>" query is run in Impala on a Hive partitioned table generates column stats on table level and is stored in TAB_COL_STATS.
> So, Executing "Alter rename <old_table> to <new_table>" after impala compute stats throws error.
> {code:java}
> ERROR : Failed
> org.apache.hadoop.hive.ql.metadata.HiveException: Unable to alter table. Cannot change stats state for a transactional table default.parqtest without providing the transactional write state for verification (new write ID 6, valid write IDs null; current state null; new state {} {code}
> The column stats generated from impala needs to be deleted for alter command to work.
