# Bug#19316063: MAKE MTS WORK WITH RELAY_LOG_RECOVERY=1 WHEN
# GTID IS ENABLED
#
# Problem:
# ========
# When gaps are present in MTS and trying to restart the server with
# relay-log-recovery=1 will result in the following error.
# "relay-log-recovery cannot be executed when the slave was stopped with an
# error or killed in MTS mode"
#
# Test:
# =====
# Enable GTID protocol along with MTS. Generate gaps in MTS, on the slave and
# restart slave server with relay-log-recovery=1. The gaps should
# be filled because of GTID protocol and slave should be in sync with master.
