[ http://issues.apache.org/jira/browse/HADOOP-285?page=all ]
Hairong Kuang reassigned HADOOP-285:
------------------------------------
Assign To: Hairong Kuang
> Data nodes cannot re-join the cluster once connection is lost
> -------------------------------------------------------------
>
> Key: HADOOP-285
> URL: http://issues.apache.org/jira/browse/HADOOP-285
> Project: Hadoop
> Type: Bug
> Components: dfs
> Versions: 0.3.0
> Reporter: Konstantin Shvachko
> Assignee: Hairong Kuang
>
> A data node looses connection to a name node and then tries to offerService() again.
> HADOOP-270 changes force it to start dataXceiveServer, which is already started and in this case
> throws IllegalThreadStateException, which goes on in a loop, and never reaches the heartbeat section.
> So the data node never re-joins the cluster, while from the out side it looks it's still running.
> This is another reason why we see missing data, and don't see failed data nodes.
