Non DFS Utilization shows same post cleanup of local filesystem

New Contributor

Initially when the environment was built there were around 327.33 GB out of total 1 TB Disk Capacity

Hence the HDFS dfsadmin report showed non-dfs usage as 327.33 GB

But after cleaning up of 300GB of on data from the Fileystem , dfsadmin report still show the non-dfs usage as 327.33 GB itself , while the reserved diskspace is 10GB

how could i get the Non-DFS utilisation refreshed post clean-up of local files on Linux Filesystem ?

hdfs dfsadmin -report

Have you clean up files under dfs.datanode.data.dirs that is not being written by HDFS for blocks? If not, the non-dfs used won't change.
