-------------------------------
Resolution: Not A Problem
> Master-Master Replication
> -------------------------
>
> Key: HBASE-21337
> URL: https://issues.apache.org/jira/browse/HBASE-21337
> Project: HBase
> Issue Type: Bug
> Components: Replication
> Affects Versions: 2.0.0
> Environment: Cluster A-HDP 3.0.0(hadoop3.0, hbase2.0); cluster
> B-native hadoop2.7, hbase1.2.6.
> Reporter: Liudong
> Priority: Major
>
> Cluster A-HDP 3.0.0(hadoop3.0, hbase2.0); cluster B-native hadoop2.7,
> hbase1.2.6.
> I want to replicate a table named T(only one CF named 'f') on cluster A and B
> with each other, that is, the table T data of A changes will be synchronized
> to B, and the table T data of B changes will be synchronized to A. I
> configured repplication both on Cluster A and B for table T using 'add_peer'
> and 'enable_table_replication' by Hbase shell(firstly A to B,2ndly B to
> A).Then，I did test in Hbase shell as below,
> 1.Put a record by typing "put 'T','r1','f:a','1'" on A,then Scan table T,it's
> no problem,the record can be found on both A and B;
> 2.Put a record by typing "put 'T','r2','f:a','1'" on B,no problem,both found
> on A and B;
> 3.Put a record by typing "put 'T','r1','f:a','2'" to update the value to '2'
> on A,no problem, updated successfully on both A and B;
> 4.Put a record by typing "put 'T','r1','f:a','3'" to update the value to '3'
> on B,no problem, updated successfully on both A and B;
> 5.Put a record by typing "put 'T','r1','f:a','4'" to update the value to '4'
> on A,the problem was coming, there is no update both A and B, that means this
> 'Put'is not effected,the value is still '3' on A and B although the Hbase
> shell does not give an error when I 'put'.
> 6.after about 1 minute, I typing the 'Put' again to update the value to '4'
> on A, now, it's successful, the value is updated to '4' both on A and B.
> May I ask what's the reason? Anything I missed to configure?Thx.
