Summary: Quota not working when append a file for HDFS-3.3.6
cluster
Key: HDFS-17206
URL: https://issues.apache.org/jira/browse/HDFS-17206
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 3.3.6, 3.2.4
Reporter: Ke Han
When running hdfs 3.3.6 cluster, I noticed that the quota doesn't work properly.
I have a file whose size is 32KB, and I set the quota to 80 KB. First, I upload
it to the hdfs, there should still be 48 KB of space left. But when I try to
append the same file to the previous file, it failed with exception
*appendToFile: Quota by storage type : DISK on path : /GvvSzRSH is exceeded.
quota = 80 KB but space consumed = 255.94 MB*
This is the first file I uploaded, so there should only be 32KB be used. But it
prompts {*}255.94MB{*}.
Reproduce
Start up a 4 node hdfs-3.3.6 cluster (latest release version), execute the
following commands
{code:java}
bin/hdfs dfs -mkdir /GvvSzRSH
bin/hdfs dfsadmin -setSpaceQuota 81920 -storageType DISK /GvvSzRSH/
bin/hdfs dfsadmin -setSpaceQuota 81920 -storageType PROVIDED /GvvSzRSH/
bin/hdfs dfs -put -p /tmp/upfuzz/hdfs/dBJShMmu/G /GvvSzRSH/
bin/hdfs dfs -appendToFile /tmp/dBJShMmu/G /GvvSzRSH/G
# appendToFile: Quota by storage type : DISK on path : /GvvSzRSH is exceeded.
quota = 80 KB but space consumed = 255.94 MB
bin/hdfs dfs -count -q -h -v -x -t DISK /GvvSzRSH/
# q or u option is given, the -x option is ignored.
# DISK_QUOTA REM_DISK_QUOTA PATHNAME
# 80 K 80 K /GvvSzRSH{code}
/tmp/dBJShMmu/G is a file with size 32B. I have attached the dir to this
failure report.
