Hi,

PFB a sample snapshot from the Name Node UI.

The Non-DFS used is showing such a huge value, but there are no files, logs etc in the hadoop directories (dfs.data.dir or dfs.datanode.data.dir).

So where does this data come from?

And, for example, the total space in the node that I use (example Node 2.com) is itself 520 GB and the space allocated to the hadoop directory(dfs.data.dir ) is 420 GB. So from where does the values 1.27 TB and 886.14 GB come from?

Please clarify and let me know how this could be resolved. Thanks!
