Subject [jira] Commented: (HBASE-1133) Master does not reload META on IOE
Date Sun, 18 Jan 2009 02:24:59 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1133?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12664910#action_12664910
] 

Andrew Purtell commented on HBASE-1133:
---------------------------------------

Needed to up FD limit again. Meantime, datanodes had trouble and some were restarted. After,
all datanodes were up and reporting to namenode within time limits again, but MetaScanner
was unhappy, throwing the IOE above. Is there anything that can be done on IOE in MetaScanner
like this? If not, never mind.
