I started to get today this message when trying to check folder size in HDFS .
hadoop fs -du -s -h /data/
using cloudera 5.11 .
The only thing that happen yesterday was deleting huge ammount of data from the HDFS .
Note - I'm using hadoop snapshots to backup the HDFS may it be related ?
Did not happen on CDH 5.4.3 with snapshots as well .
Any help will be appreciated.
