Much appreciated. Thank you for the name node heap tuning link as well. I am busy checking it out and will post an updated.</P><P>&nbsp;</P><P>During my investigation yesterday, I also found out there were millions of pending deletes. As I mentioned, I deleted about 23 million blocks down to about 1400. The JMX console says there still are about 11 million blocks still waiting to be deleted - I'm assuming the blockreport would also account for these until they are actually deleted? Could that be a reason why its still slow?</P><P>Its deleting about 600 nodes/second which seems okay, but I guess it will be a while until everything is deleted. Is this normal?</P><P>&nbsp;</P><P>&nbsp;</P> Tue, 29 Oct 2019 10:02:53 GMT Elephanta 2019-10-29T10:02:53Z
