Xiaoyu Yao updated HDFS-7701:
-----------------------------
Description:
"hadoop fs -count -q" currently shows name space/disk space quota and remaining
quota information. With HDFS-7584, we want to display per storage type quota
and its remaining information as well.
The current output format as shown below may not easily accomodate 6 more
columns = 3 (existing storage types) * 2 (quota/remaining quota). With new
storage types added in future, this will make the output even more crowded.
There are also compatibility issues as we don't want to break any existing
scripts monitoring hadoop fs -count -q output.
$ hadoop fs -count -q -v /test
QUOTA REM_QUOTA SPACE_QUOTA REM_SPACE_QUOTA DIR_COUNT
FILE_COUNT CONTENT_SIZE PATHNAME
none inf 524288000 524266569 1
15 21431 /test
Propose to add -t parameter to display ONLY the storage type quota information
of the directory in the separately. This way, existing scripts will work as-is
without using -t parameter.
1) When -t is not followed by a specific storage type, quota and usage
information for all storage types will be displayed.
$ hadoop fs -count -q -t -h -v /test
SSD_QUOTA REM_SSD_QUOTA DISK_QUOTA REM_DISK_QUOTA
ARCHIVAL_QUOTA REM_ARCHIVAL_QUOTA PATHNAME
512MB 256MB none inf none
inf /test
2) If -t is followed by a storage type, only the quota and remaining quota of
the storage type is displayed.
$ hadoop fs -count -q -t SSD -h -v /test
SSD_QUOTA REM_SSD_QUOTA PATHNAME
512 MB 256 MB /test
