Subject [jira] [Commented] (HBASE-18352) Enable Replica tests that were disabled by Proc-V2 AM in HBASE-14614
Date Mon, 23 Oct 2017 17:35:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18352?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16215502#comment-16215502

Yi Liang commented on HBASE-18352:

I saw another situation that may cause random assignment. When we restart hbase, if we start
master first, and then regionservers.
Once one region server count in, master will start to begin region assignment. There is a
possibility that the assign plan is created for a region before its last region server up,
so AM will randomly chose one region servers for this region.
