Cluster A-HDP 3.0.0(hadoop3.0, hbase2.0); cluster B-native hadoop2.7, hbase1.2.6.
Description
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.
