Subject [jira] [Created] (HBASE-8566) Master-Slave replication: truncate action isn't sent over to slave cluster and cause data inconsisten
Date Thu, 16 May 2013 22:39:15 GMT
Demai Ni created HBASE-8566:
-------------------------------

             Summary: Master-Slave replication: truncate action isn't sent over to slave cluster
and cause data inconsisten
                 Key: HBASE-8566
                 URL: https://issues.apache.org/jira/browse/HBASE-8566
             Project: HBase
          Issue Type: Bug
          Components: Replication
    Affects Versions: 0.94.3
         Environment: two 2-nodes clusters setup as Master and Slave for replication of table
'usertable'
            Reporter: Demai Ni
            Priority: Minor


after successfully setup the replcation. put some rows into 'usertable' , 

At Master cluster
$truncate 'usertable'

The truncate(or mass delete from user perspective) request isn't sent over to slave cluster.


>From internal, the truncate is 'disable', 'drop' and 'create'. Such operations are not
designed for replication. However, from external/user perspective, this is a 'delete everything'
operation, which should be part of the replication. 

This JIRA is to add this support
---------------------------
additional information. I did a few loads using YCSB into 'usertable', with different # of
rows(from 1000 to 100000). And did truncate a couple times in between. Then the slave cluster
began to throw errors:
{code:title=count failed on slave cluster|borderStyle=solid}
