Konstantin Shvachko commented on HADOOP-6857:
---------------------------------------------
*Scenario 1* looks rather unusual, but again this is how quotas are counted:
When you modify a file in a snapshot, then it is counted twice for quotas. Even
if it doesn't actually store axtra blocks. If people want to change this, it
should be a different jira related to qoutas. I don't think anything needs to
be fixed in this regard here.
*Scenario 2* indeed gives inconsistent results for _du_ and _dus_, because _du_
resolves path to point to the current tree rather than to the snapshot
contents. This doesn't look right to me.
> FsShell should report raw disk usage including replication factor

> Currently FsShell report HDFS usage with "hadoop fs -dus <path>" command.
> Since replication level is per file level, it would be nice to add raw disk
> usage including the replication factor (maybe "hadoop fs -dus -raw <path>"?).
> This will allow to assess resource usage more accurately. -- Alex K
