Subject [jira] Resolved: (HBASE-1074) New thread introduced by hbase-900 part 4 is not daemon so can cause JVM to stick around on abort
Date Sun, 21 Dec 2008 03:54:44 GMT

     [ https://issues.apache.org/jira/browse/HBASE-1074?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

stack resolved HBASE-1074.
--------------------------

    Resolution: Fixed

Also, unrelated, changed refresh rate on UI from 30 seconds to 5minutes.  Invariably on crash
the UI has just refreshed when I want to see last state.
