Subject [jira] [Created] (HDFS-8092) dfs -count -q should not consider snapshots under REM_QUOTA
Date Wed, 08 Apr 2015 07:56:13 GMT
Archana T created HDFS-8092:
-------------------------------

             Summary: dfs -count -q should not consider snapshots under REM_QUOTA
                 Key: HDFS-8092
                 URL: https://issues.apache.org/jira/browse/HDFS-8092
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: snapshots, tools
            Reporter: Archana T
            Priority: Minor


dfs -count -q should not consider snapshots under Remaining quota

List of Operations performed-
1. hdfs dfs -mkdir /Dir1
2. hdfs dfsadmin -setQuota 2 /Dir1
3. hadoop fs -count -q -h -v /Dir1
 
       QUOTA       {color:red} REM_QUOTA{color}      SPACE_QUOTA REM_SPACE_QUOTA    DIR_COUNT
  FILE_COUNT       CONTENT_SIZE PATHNAME
           2               {color:red} 1 {color}            none             inf         
  1            0                  0 /Dir1

4. hdfs dfs -put hdfs /Dir1/f1
5. hadoop fs -count -q -h -v /Dir1
     QUOTA       {color:red} REM_QUOTA{color}      SPACE_QUOTA REM_SPACE_QUOTA    DIR_COUNT
  FILE_COUNT       CONTENT_SIZE PATHNAME
           2              {color:red}  0{color}             none             inf         
  1            1             11.4 K /Dir1
6. hdfs dfsadmin -allowSnapshot /Dir1
7. hdfs dfs -createSnapshot /Dir1
8. hadoop fs -count -q -h -v /Dir1

 QUOTA       {color:red} REM_QUOTA{color}      SPACE_QUOTA REM_SPACE_QUOTA    DIR_COUNT  
FILE_COUNT       CONTENT_SIZE PATHNAME
           2             {color:red}  -1 {color}            none             inf         
  2            1             11.4 K /Dir1

Whenever snapshots created the value of REM_QUOTA gets decremented.

When creation of snaphots are not considered under quota of that respective dir then dfs -count
should not decrement REM_QUOTA value
