Subject [jira] [Commented] (HBASE-4687) regionserver may miss zk-heartbeats to master when replaying edits at region open
Date Thu, 27 Oct 2011 20:28:34 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4687?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13137495#comment-13137495
] 

Prakash Khemani commented on HBASE-4687:
----------------------------------------

The progress reporter in this case heartbeats to the master via zk and
therefore I had called them zk-heartbeats. I know realize that calling
them zk-heartbeats easily confuses matters with the region server's "I am
Alive" zk-heartbeat.

In this case, master has put up the zk node /hbase/UNASSIGNED/<region> and
is waiting for the rs to open the region. The rs, while opening the
region, keeps updating that zk node to let the master know of that region
open is progressing.

> replayRecoveredEdits() should do another reporter.progress() before returning.
