HDFS not reclaiming the freed up disk space


HDFS not reclaiming the freed up disk space

New Contributor

Hello friends,

I'm in a trouble. My production hadoop cluster HDFS disk utilization is increasing drastically and no housekeeping activity is helping. Actually, I have deleted lot of big size files from hdfs using skipTrash option but the directory is still showing the same size that was before deletion. I have checked the utilization even after 24 hours of file deletion but same situation. I have restarted Ambari metrics services from Ambari and all other component services from all the nodes. However, the disk utilization is still not improved.


I'm not a hadoop admin. Please suggest what can be the reason.
