> 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.
