# 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.
