Subject [jira] [Commented] (HBASE-9457) Master could fail start if region server with system table is down
Date Tue, 10 Sep 2013 00:51:52 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9457?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13762535#comment-13762535
] 

Jesse Yates commented on HBASE-9457:
------------------------------------

bq. perspective of a metrics table, updates will be done by the system itself so retries have
a different effect on the system. Which may be unacceptable in some scenarios?

IMO, we can lose some stats - they are a best effort and its ok if they are off by a bit (this
may be revised later, but that's generally the way people approach stats). I'd say lets go
with the expected behavior for startup, esp if Jimmy is gonna do the work :), and change it
back later if we need to.

> In the region server holding the system table is killed while master is starting, master
will hang there waiting for system table to be assigned which won't happen.
