[jira] [Commented] (HBASE-11201) Enable global procedure members to
return values to procedure master
[ https://issues.apache.org/jira/browse/HBASE-11201?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14017075#comment-14017075 ]

----------------------------------
Hi, [~yuzhihong@gmail.com]
I attached addendum-allow-null-data-from-member.patch. This makes the master coordinator tolerate null data from the procedure member.
It will help in such case:
The hmaster is updated with the patch, but some region servers have not.
After this addendum, snapshot (or old procedure) will not fail during the scenario described.

> Currently in the global procedure framework, the procedure coordinator can send data (procedure argument) to the members when starting procedure.
> But we don't support getting data returned from the procedure members back to the master.
> Similar to RPC and normal procedure/function calls, in many cases, this is a useful capability.
> The infrastructure is in place. We just need to plug in the holes and make it happen.
