Subject [jira] Commented: (HADOOP-2159) Namenode stuck in safemode
Date Wed, 21 May 2008 22:55:56 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2159?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12598844#action_12598844

Hairong Kuang commented on HADOOP-2159:
---------------------------------------

Please note that the cluster did have stale blocks. The ratio of the minimally replicated
blocks to the total number of valid blocks is greater than 100%,

>                 Key: HADOOP-2159
>                 URL: https://issues.apache.org/jira/browse/HADOOP-2159
>             Project: Hadoop Core
>          Issue Type: Bug
>          Components: dfs
>    Affects Versions: 0.16.0
>            Reporter: Christian Kunz
>
> Occasionally (not easy to reproduce) the namenode does turn off safemode automatically,
although fsck does not report any missing or under-replicated blocks (safemode threshold set
to 1.0).
> At this moment I do not have any additional information which could help analyze the
issue.
