Subject [jira] [Commented] (HBASE-18367) Reduce ProcedureInfo usage
Date Fri, 14 Jul 2017 22:20:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18367?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16088196#comment-16088196

stack commented on HBASE-18367:

Making getState and isRunnable public seems small price to pay if can remove use of PI.

Maybe s/CompletedProcedure/CompletedProcedureRetainer/ since it not a Procedure... it just
has one?

Should we add a method to the CompletedProcedure or whatever its called that is like this:

boolean evict(long now);

... and inside it, it would do all the checks you have here:

189	        if ((completedProcedure.hasClientAckTime() && (now - completedProcedure.getClientAckTime())
>= evictAckTtl) ||
190	            (now - proc.getLastUpdate()) >= evictTtl) {

Why a FailedProcedure ?

Nice cleanup in ProcedureStore and in ProcedureWALFormatReader

This looks like a good direction to me [~balazs.meszaros]

> If we want to replace ProcedureInfo objects with jsons (HBASE-18106) we have to reduce
ProcedureInfo usage. Currently it is used several places in the code where it could be replaced
with Procedure (e.g. ProcedureExecutor). We should use ProcedureInfo only for the communication
before removing it.
