Maddineni Sukumar commented on HBASE-16466: ------------------------------------------- And I fixed below two minor issues found during this in this same patch(I hope its fine, if not i will put diff patch) #HBASE-17900 - VerifyReplication - input param variables declared as static causing issues to run VerifyReplication multiple times in single JVM(mainly for unit tests) #HBASE-17899 - VerifyReplication not exiting for invalid arguments even though we have check for it. > HBase snapshots support in VerifyReplication tool to reduce load on live > HBase cluster with large tables > -------------------------------------------------------------------------------------------------------- > > Key: HBASE-16466 > URL: https://issues.apache.org/jira/browse/HBASE-16466 > Project: HBase > Issue Type: Improvement > Components: hbase > Affects Versions: 0.98.21 > Reporter: Sukumar Maddineni > Assignee: Maddineni Sukumar > Fix For: 2.0.0 > > Attachments: HBASE-16466.branch-1.3.001.patch, HBASE-16466.v1.patch, > HBASE-16466.v2.patch, HBASE-16466.v3.patch > > > As of now VerifyReplicatin tool is running using normal HBase scanners. If > you want to run VerifyReplication multiple times on a production live > cluster with large tables then it creates extra load on HBase layer. So if we > implement snapshot based support then both in source and target we can read > data from snapshots which reduces load on HBase -- This message was sent by Atlassian JIRA (v6.3.15#6346)
