+ * gets into the related table in UTIL1, then also validates the same got replicated to cluster
+ * UTIL2. Then, bulk loads another file into UTIL2, and checks if related values are present on
+ * UTIL2, and also gets replicated to UTIL1.
+ * It also defines a preBulkLoad coprocessor that is added to all test table regions on each of the
+ * clusters, in order to count amount of times bulk load actually gets invoked. This is to certify
+ * we are not entered in the infinite loop condition addressed by HBASE-22380.

 Review comment:
   The 400 is time for replication to run? Will this make test a little flakey?
