[hbase] when the master times out a region server's lease, it is too aggressive in reclaiming the server's log --------------------------------------------------------------------------------------------------------------
Key: HADOOP-1937 URL: https://issues.apache.org/jira/browse/HADOOP-1937 Project: Hadoop Issue Type: Bug Components: contrib/hbase Affects Versions: 0.15.0 Reporter: Jim Kellerman Assignee: Jim Kellerman Fix For: 0.15.0 When a region server's lease times out, the master immediately begins trying to split the server's log file. There have been cases where a region server was just a little late reporting to the master and the master had already started trying to reclaim the server's log, even though the server was still writing to it. There needs to be some kind of "grace period" in which, if the region server reports in, the master re-instates the server. If the "grace period" expires, then the master should start processing the server's log. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
