Subject [jira] [Commented] (HDFS-2756) Warm standby does not read the in_progress edit log
Date Fri, 06 Jan 2012 01:07:39 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2756?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13181012#comment-13181012

Aaron T. Myers commented on HDFS-2756:

Hey Suresh, see [this comment|https://issues.apache.org/jira/browse/HDFS-1975?focusedCommentId=13131219&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13131219]
where Jitendra mentions that {{FileJournalManager}} should not return in-progress streams,
and HDFS-2737 where Todd discusses the need to roll edit logs periodically since the standby
can only read finalized streams.
