Jianwei Cui commented on HBASE-16423: ------------------------------------- Thanks for the review [~tedyu], could you please take a look at the patch for branch-1? > Add re-compare option to VerifyReplication to avoid occasional inconsistent > rows > -------------------------------------------------------------------------------- > > Key: HBASE-16423 > URL: https://issues.apache.org/jira/browse/HBASE-16423 > Project: HBase > Issue Type: Improvement > Components: Replication > Affects Versions: 2.0.0 > Reporter: Jianwei Cui > Assignee: Jianwei Cui > Priority: Minor > Fix For: 2.0.0, 1.4.0 > > Attachments: HBASE-16423-branch-1-v1.patch, HBASE-16423-v1.patch, > HBASE-16423-v2.patch, HBASE-16423-v3.patch > > > Because replication keeps eventually consistency, VerifyReplication may > report inconsistent rows if there are data being written to source or peer > clusters during scanning. These occasionally inconsistent rows will have the > same data if we do the comparison again after a short period. It is not easy > to find the really inconsistent rows if VerifyReplication report a large > number of such occasionally inconsistency. To avoid this case, we can add an > option to make VerifyReplication read out the inconsistent rows again after > sleeping a few seconds and re-compare the rows during scanning. This behavior > follows the eventually consistency of hbase's replication. Suggestions and > discussions are welcomed. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
