|When using Cloudera Manager Reports Manager to check the space usage of directory /data, the values shown in "Current Disk Usage By Directory" are:|
data 9.3 TiB 28.0 TiB
After converting 28TiB to bytes:
28TiB = 1099511627776*28 = 30786325577728 bytes
However, when execute Hadoop CLI tool du for the same directory, the value below is shown:
hdfs dfs -du / | grep data
14795860820650 62191790304036 /data
It looks like the value from du is more than twice as big as what reports in the Reports Manager.
