# This test evaluates that recovery fails properly when the donors available
# have conflicting data.
#
# The test steps are:
# 0) The test requires two servers: M1 and M2.
# 1) Bootstrap start M1. Create table t1 and insert some data for recovery.
# 2) Create table t1 on M2 before starting. Start GR on M2.
# 3) With a low number of retries watch recovery fail on M2. It should go
# to ERROR state.
# 4) Remove the data in the joiner M2 and restart GR. All is OK. Validate
# data.
# 5) Clean up.
