Subject [jira] Commented: (HADOOP-2159) Namenode stuck in safemode
Date Tue, 06 Nov 2007 17:48:50 GMT

Owen O'Malley commented on HADOOP-2159:
---------------------------------------

I would check for floating point precision problems. If the calculation was done carelessly,
you may end up not being able to reach the desired goal of 1.0.

>                 Key: HADOOP-2159
>                 URL: https://issues.apache.org/jira/browse/HADOOP-2159
>             Project: Hadoop
>          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.
