Subject [jira] Resolved: (HADOOP-3132) DFS writes stuck occationally
Date Tue, 22 Apr 2008 17:05:22 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-3132?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Raghu Angadi resolved HADOOP-3132.
----------------------------------

    Resolution: Won't Fix

I tried couple of more times to reproduce this case but could not. The cluster was rebooted
and bios settings were changed a little bit (for unrelated reasons). Not sure if reboots helped.
We can open it again if we notice this again.

> This problem happens in 0.17 trunk
> As reported in hadoop-3124,
> I saw reducers waited 10 minutes for writing data to dfs and got timeout.
> The client retries again and timeouted after another 19 minutes.
> During the period of write stuck, all the nodes in the data node pipeline were functioning
fine.
> The system load was normal.
> I don't believe this was due to slow network cards/disk drives or overloaded machines.
> I believe this and hadoop-3033 are related somehow.
