Subject [jira] [Created] (HBASE-16419) check REPLICATION_SCOPE's value more stringent
Date Tue, 16 Aug 2016 05:53:20 GMT
Guangxu Cheng created HBASE-16419:
-------------------------------------

             Summary: check REPLICATION_SCOPE's value more stringent
                 Key: HBASE-16419
                 URL: https://issues.apache.org/jira/browse/HBASE-16419
             Project: HBase
          Issue Type: Bug
          Components: master
    Affects Versions: 1.2.2, 2.0.0
            Reporter: Guangxu Cheng


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´╝îthe exceptions as follow:
