fs.trash.interval and this fails to auto purge trash folder
Sunil Kumar Chakrapani created HADOOP-15880:
-----------------------------------------------
Summary: WASB doesn't honor fs.trash.interval and this fails to auto purge trash folder
Key: HADOOP-15880
URL: https://issues.apache.org/jira/browse/HADOOP-15880
Project: Hadoop Common
Issue Type: Bug
Components: fs/azure
Affects Versions: 2.7.3
Environment: Any HDInsigth cluster pointing to WASB.
Reporter: Sunil Kumar Chakrapani
when "fs.trash.interval" is set to a value, trash for the local hdfs got cleared where as the trash folder on WASB doesn't get deleted and the files get piled up on WASB store..
WASB doesn't pick up fs.trash.interval value and this fails to auto purge trash folder on WASB store.
*Issue : WASB doesn't honor fs.trash.interval and this fails to auto purge trash folder*
*Steps to reproduce Scenario:*
*Delete any file stored on HDFS*
hdfs dfs -D "fs.default.name=hdfs://mycluster/" -rm /hivestore.txt
18/10/23 06:18:05 INFO fs.TrashPolicyDefault: Moved: 'hdfs://mycluster/hivestore.txt' to trash at: hdfs://mycluster/user/sshuser/.Trash/Current/hivestore.txt
*When deleted the file is moved to trash folder*
hdfs dfs -rm wasb:///hivestore.txt
18/10/23 06:19:13 INFO fs.TrashPolicyDefault: Moved: 'wasb://kcspark-2018-10-18t17-07-40-524z@kcdnsproxy.blob.core.windows.net/hivestore.txt' to trash at: wasb://kcspark-2018-10-18t17-07-40-524z@kcdnsproxy.blob.core.windows.net/user/sshuser/.Trash/Current/hivestore.txt
*Reduced the fs.trash.interval from 360 to 1 and restarted all related services.*
*Trash for the local hdfs gets cleared honoring the "fs.trash.interval" value.*
hdfs dfs -D "fs.default.name=hdfs://mycluster/" -ls hdfs://mycluster/user/sshuser/.Trash/Current/
ls: File hdfs://mycluster/user/sshuser/.Trash/Current does not exist.
*Where as the trash for WASB doesn't get cleared.*
hdfs dfs -ls wasb://kcspark-2018-10-18t17-07-40-524z@kcdnsproxy.blob.core.windows.net/user/sshuser/.Trash/Current/
