# ==== Purpose ====
#
# This test script serves as the functionality testing for
# WL#6120- Change master without stopping Slave threads.
#
# This test script does the following:

#  - Temporary table(s) should NOT be dropped if applier is running during
#    CHANGE MASTER.
#  - If there are open temporary tables and there is a STOP SLAVE/
#    STOP SLAVE[IO_THREAD/SQL_THREAD]there should be a warning.
#  - If there are open temporary tables and there is a CHANGE MASTER,
#    there should be a warning.
#  - There is no warning if the change master option only changes connection
#    or execution configuration.
#
#  ==== Related Worklog(s) And Bug(s)====
