After a new installation, the /tmp/mysql_install.log on the UM1 contains the following errors:

[root@columnStore ~]# cat /tmp/mysql_install.log
ERROR 1305 (42000) at line 16: FUNCTION mysql.caldisablepartitions does not exist
ERROR 1305 (42000) at line 17: FUNCTION mysql.calenablepartitions does not exist
ERROR 1305 (42000) at line 18: FUNCTION mysql.caldroppartitions does not exist
ERROR 1305 (42000) at line 19: FUNCTION mysql.calshowpartitions does not exist
ERROR 1305 (42000) at line 20: FUNCTION mysql.caldroppartitionsbyvalue does not exist
ERROR 1305 (42000) at line 21: FUNCTION mysql.caldisablepartitionsbyvalue does not exist
ERROR 1305 (42000) at line 22: FUNCTION mysql.calenablepartitionsbyvalue does not exist
ERROR 1305 (42000) at line 23: FUNCTION mysql.calshowpartitionsbyvalue does not exist

in the ../mysql/install_calpont_mysql.sh script, there are commands to drop some Columnstore specific functions, which does not exist on a new installations:

DROP FUNCTION caldisablepartitions;
DROP FUNCTION calenablepartitions;
DROP FUNCTION caldroppartitions;
DROP FUNCTION calshowpartitions;
DROP FUNCTION caldroppartitionsbyvalue;
DROP FUNCTION caldisablepartitionsbyvalue;
DROP FUNCTION calenablepartitionsbyvalue;
DROP FUNCTION calshowpartitionsbyvalue;

These statements caused the errors messages in the mysql_install.log file. We should add the "if exists" keywords to the statements so that a warning, instead of an error, would be returned.

MariaDB [(none)]> use mysql
Database changed
MariaDB [mysql]> drop function daniel;
ERROR 1305 (42000): FUNCTION mysql.daniel does not exist
MariaDB [mysql]> drop function if exists daniel;
Query OK, 0 rows affected, 1 warning (0.00 sec)

MariaDB [mysql]> show warnings;

1 row in set (0.00 sec)

I also noticed that are 11 DELETEs, 8 DROP FUNCTIONs, and 29 CREATE FUNCTIONs. Should they all be 29? I think we just did not keep up the list as time goes by.
