[jira] [Commented] (HBASE-19833) Refactor Servers: async, event-driven core, startup/shutdown sequencing, etc.

    [ https://issues.apache.org/jira/browse/HBASE-19833?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16333305#comment-16333305 ] 

stack commented on HBASE-19833:
-------------------------------

See HBASE-19834. It talks about how the Master startup is done inside the Master's main thread and that if we hit a blocking function, the main thread is unavailable to receive other changes in state such as cluster shutdown.
