Major Description
When create table or modify table, the master will check if the value of REPLICATION_SCOPE is less than 0, however the value of REPLICATION_SCOPE must be 0 or 1. Otherwise will lead to regionserver shutdown, so I think should be check the values of REPLICATION_SCOPE more stringent.
Beginning I don't fully understand the usage of REPLICATION_SCOPE, then set REPLICATION_SCOPE to 2 by mistake.when I insert data to table,the regionservers abort one by one,finanly
the cluster abort，the exceptions as follow:
