-------------------------------
Summary: 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
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.
