Attila Jeges updated IMPALA-9421:
---------------------------------
Description:
Show database operation takes over 3-4 seconds in impala-shell when connecting
to a coordinator using hs2-http with LDAP authentication:
{code:java}
$ impala-shell.sh --protocol='hs2-http' --ssl -i "impala-coordinator:443" -u
username -l
impala-shell> show database;

| airline_ontime_parquet | |
| default | Default Hive database |

Looks like there's a new connection and LDAP authentication for each RPC call
made which imposes an overhead.
Please investigate whether it's possible to speed things up by reusing
connections.
