Subject [jira] Commented: (HADOOP-3585) Hardware Failure Monitoring in large clusters running Hadoop/HDFS
Date Wed, 13 Aug 2008 21:42:46 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3585?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12622362#action_12622362
] 

Ioannis Koltsidas commented on HADOOP-3585:
-------------------------------------------

As pointed out by https://issues.apache.org/jira/browse/HADOOP-3949, the javadoc warnings
are due to duplicated jar files under src/contrib/chukwa/lib and trunk/lib.

As pointed out by https://issues.apache.org/jira/browse/HADOOP-3950 the failed tests are due
to TestMapRed and TestMiniMRDFSSort.

It is not clear to me yet where the release audit warnings come from. Does anyone know? They
are all for non-java configuration files under /src/contrib/failmon/conf.

Thanks

> At IBM we're interested in identifying hardware failures on large clusters running Hadoop/HDFS.
We are working on a framework that will enable nodes to identify failures on their hardware
using the Hadoop log, the system log and various OS hardware diagnosing utilities. The implementation
details are not very clear, but you can see a draft of our design in the attached document.
We are pretty interested in Hadoop and system logs from failed machines, so if you are in
possession of such, you are very welcome to contribute them; they would be of great value
for hardware failure diagnosing.
> Some details about our design can be found in the attached document failmon.doc. More
details will follow in a later post.
