I've got 4% of HDFS used by /app/hbase bit I removed hbase a year ago



So about a year ago we decided Hbase wasn't really working for us so we decided to remove it. It's not listed in the services list in Ambari any more and I think we ran a HDP upgrade since too.

HDFS is a little low on disk so I've been doing some digging about and found that /app/hbase has a footprint that works out to about 4% of the cluster with it split between



If I dig into it I can see in the folder structure the names of tables that we used to run, in retrospect maybe it would have been an idea to delete all the data before uninstalling the service but hind sight is 20/20.

What I wantto kow now is are there any risks to just deleting out the content?

I'm leaning towards not deleting the root directory so I don't screw anything up should we add Hbase back some day, but in the folders



delete the folders with the table names I no longer care about.

Does anyone have any advice on this?

If you are sure that you don't have any other data than the old hbase data(which is not needed anymore). You are safe to delete it.
