NOTE: In the examples that follow, user details, table name, company name, email, hostnames, etc. represent a fictitious sample (and are used to provide an illustrative example only). Any similarity to actual persons, or entities, living or dead, is purely coincidental and not intended in any manner.

The root filesystem is filling up with edit files under the NameNode and Journal Node current directories::

/opt/hadoop/dfs/nn/current
/opt/hadoop/dfs/jn/current


The files are not deleted from those folders.

There are some edits_inprogress files which were created seven months ago on the three journal nodes and they are not deleted automatically.
