Dear Hadoop community,
HDFS v2.7.7.
The output of du is:
# hdfs dfs -du -s -h /
*217.5 T* /
while the output of df is:
# hdfs dfs -df -h /
Filesystem Size Used Available Use%
hdfs://nameservice1 1.1 P *981.3 T* 103.2 T 86%
All files are 3 replicas, so I suppose the "Used" should be about 217.5 * 3
= *652.5 T*.
The problem is who used the other *300+T *(981.3 T - 652.5 T)? Thanks!
BTW, I found a similar issue
<https://community.cloudera.com/t5/Support-Questions/space-used-in-hdfs-is-different-from-free-space/td-p/196064>,
but I do not think the answer is correct.
