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

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
