Subject [jira] [Updated] (HBASE-18229) create new Async Split API to embrace AM v2
Date Wed, 05 Jul 2017 18:03:00 GMT

     [ https://issues.apache.org/jira/browse/HBASE-18229?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Yi Liang updated HBASE-18229:
    Attachment: hbase-18229-master-v6.patch

Hi GuangHao,
   Thanks for let me know, will rebase with the latest code.

I upload the new patch, it now can pass TestShell on my local machine. And I also test all
the test cases, all related test cases pass
For your question:
Is HBASE-17480 the issue for cleaning out unused split code?
That jira is to revisit split procedure step, which is to move the old splitting logic based

I plan to clean the unused class and photobuf that was used when split request go to RSrpcSevrice,
they are not used anymore when split request directly  send to MasterRpcServices.

> See HBASE-18105 for related information,  this jira will change the logic of Path 1 in
splitProcedure, the execution path will be:
> *HBaseAdmin.splitRegionAsync -> MasterKeepAliveConnection.splitRegion  ->  MasterRpcServices.splitRegion
 ->  HMaster.splitRegion-> AssignmentManager.submitProcedure*
> Master Will no longer ask Rs and then Rs turn around to ask master to do the split operation.
