Subject [jira] [Created] (HBASE-11908) Region replicas should be added to the meta table at the time of table creation
Date Sun, 07 Sep 2014 00:05:28 GMT
Enis Soztutar created HBASE-11908:
-------------------------------------

             Summary: Region replicas should be added to the meta table at the time of table
creation
                 Key: HBASE-11908
                 URL: https://issues.apache.org/jira/browse/HBASE-11908
             Project: HBase
          Issue Type: Sub-task
            Reporter: Enis Soztutar
            Assignee: Enis Soztutar
             Fix For: 2.0.0


While testing async replication handling and failover handling for region replicas, we've
found that sometimes the secondary region replicas do not open and update meta quickly enough,
and hence meta would not contain any information about the region replica id. 

If a reader caches the meta row before all region replicas are open the first time (such as
the async wal replication endpoint), then it may miss the region replica and won't know about
it until it refreshes it's cache again. 

Instead, we should add entries to the meta for all of the region replicas at the time of create
table (just like primary regions).
