[jira] Updated: (HBASE-496) impossible state for createLease over
and over again for hours
[ https://issues.apache.org/jira/browse/HBASE-496?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
stack updated HBASE-496:
------------------------
Attachment: 12-0.16.0.patch
This is like HBASE-12 but let this issue just address the fact that we retry w/o pause. The retries are putting such a load on the master, its not able to do much else.
This patch should fix the issue. We were not pausing between retries.
