Raghu Angadi updated HADOOP-6012:
---------------------------------
Attachment: HADOOP-6012.patch
Attached patch fixed above issues.
Help message:
* Before : {noformat} $ bin/hdfs dfsadmin -help -setSpaceQuota
-setSpaceQuota <quota> <dirname>...<dirname>: Set the disk space quota <quota>
for each directory <dirName>.
The directory quota is a long integer that puts a hard limit
on the number of names in the directory tree.
Quota can also be speciefied with a binary prefix for terabytes,
petabytes etc (e.g. 50t is 50TB, 5m is 5MB, 3p is 3PB).
[...] {noformat}
* After : {noformat} $ bin/hdfs dfsadmin -help setSpaceQuota
-setSpaceQuota <quota> <dirname>...<dirname>: Set the disk space quota <quota>
for each directory <dirName>.
The space quota is a long integer that puts a hard limit
on the total size of all the files under the directory tree.
The extra space required for replication is also counted. E.g.
a 1GB file with replication of 3 consumes 3GB of the quota.
Quota can also be speciefied with a binary prefix for terabytes,
petabytes etc (e.g. 50t is 50TB, 5m is 5MB, 3p is 3PB).

> There are a few issues with quotas help messages.
> Space Quotas :
> # It is not clear to the users that space quota counts replication as well.
> i.e. with a replication of 3, user needs 3GB of quota to be able to write 1GB
> file. should makes this explicit in the message
> # There is a cut-n-paste error in the help message.
> All quota commands :
> * user needs to type {{'dfsadmin \-help \-setQuota'}} (note '\-'before
> setQuota), where as for the rest of the dfsadmin (and fs) commands '-' is not
> required. Should make this consistent.
> Since this is documentation only fix, I would like to commit it to 0.20.1
> also.
