I have learned that it is not a recommended option to increase the percentage for&nbsp;<SPAN>"yarn.nodemanager.disk-health-checker.max-disk-utilization-per-disk-percentage"</SPAN>. And more over the disk space has already reached 98%. I think I need to free some disk space. But was just curious what kind of data can I be able to clear in the data directory. Any suggestions.&nbsp;</P><P>2. Can there be a scenario that a Rouge yarn application is filling up the data in that particular data node. If so how can I check that.&nbsp;</P><P>Thanks in Advance.&nbsp;</P> Tue, 14 Jan 2020 21:02:45 GMT nk_11 2020-01-14T21:02:45Z
