Jason Fehr updated IMPALA-13322:
--------------------------------
Description:
When running "alter table add column if not exists" ddls on
sys.impala_query_live, Impala returns "IllegalStateException: null". No stack
trace can be found in any log files.
Even though that error was returned, the column was still added, it just took
about 10 seconds to show up in the table.
Once this issue is fixed, the disparate logic to handle upgrades on
sys.impala_query_log and sys.impala_query_live can be unified.
