[jira] [Created] (HBASE-26926) VerifyReplication should use region startKey to check PeerTable

[Yulin Niu (Jira)]

 Summary: VerifyReplication should use region startKey to check 
PeerTable
 Key: HBASE-26926
 URL: https://issues.apache.org/jira/browse/HBASE-26926
 Project: HBase
  Issue Type: Bug
  Components: mapreduce, Replication
Reporter: Yulin Niu
Assignee: Yulin Niu


 
[https://github.com/apache/hbase/blob/master/hbase-mapreduce/src/main/java/org/apache/hadoop/hbase/mapreduce/replication/VerifyReplication.java#L199]

Here we miss the case: peer table has redundant data, which are all smaller 
than the source table first rowkey

The basic idea is add a role "CompactionServer" to take the Compaction job. 
HMaster is responsible for scheduling the compaction job to different 
CompactionServer.

Suggestions are welcomed. Thanks.

should not be created by users themselves.

[DISCUSS] the IA annotation on hbase client exceptions

[Yulin Niu]

Hi, guys:

There are IA.Public and also IA.Private under the hbase-client  exceptions
package, whether the IA.Private exceptions should be IA.Public?
e.g.MasterRegistryFetchException, OutOfOrderScannerNextException
,RegionMovedException,RegionOpeningException
And any others thing about the IA annotation on exceptions?
FYI 2538
