> Datanode stops cleaning disk space
> ----------------------------------
>                 Key: HDFS-63
>                 URL: https://issues.apache.org/jira/browse/HDFS-63
>             Project: Hadoop HDFS
>          Issue Type: Bug
>         Environment: Linux
>            Reporter: Igor Bolotin
>            Priority: Critical
> Here is the situation - DFS cluster running Hadoop version 0.19.0. The cluster is running
on multiple servers with practically identical hardware. 
> Everything works perfectly well, except for one thing - from time to time one of the
data nodes (every time it's a different node) starts to consume more and more disk space.
The node keeps going and if we don't do anything - it runs out of space completely (ignoring
20GB reserved space settings). 
> Once restarted - it cleans disk rapidly and goes back to approximately the same utilization
as the rest of data nodes in the cluster.
