How to find the used cache in HDFS

0 votes

I am executing the Hadoop dfsasmin -report command. I am getting the below output:

hdfs dfsadmin -report
Configured Capacity: 1593717043200 (1.45 TB)Present 
Capacity: 1508940406648 (1.37 TB)
DFS Remaining: 604831743864 (563.29 GB)
DFS Used: 904108662784 (842.02 GB)
DFS Used%: 59.92%
Under replicated blocks: 16
Blocks with corrupt replicas: 0
Missing blocks: 0
Missing blocks (with replication factor 1): 0

Can anyone help me in understanding how can I find the Cache used?

hdfs dfsadmin -report 

This command tells fs information & stats. You can use flag to filter the details about the specific DataNode.

The Cache Used% depends on the configured cache. If  you haven’t configured the cache capacity, you’ll get the value as 100%.
