Zhe Zhang created HDFS-8304:
-------------------------------
Summary: Separate out shared log purging methods for QJM (Paxos
directory) and FJM
Key: HDFS-8304
URL: https://issues.apache.org/jira/browse/HDFS-8304
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Zhe Zhang
Assignee: Zhe Zhang
With HDFS-8303 QJM will purge its /current dir through FJM. However its Paxos
dir needs to be purged separately.
QJM currently uses its own {{JNStorage#purgeMatching}} method while FJM calls
{{matchEditLogs}} to find all matches first and then uses
{{DeletionStoragePurger#purgeLog}}.
This JIRA aims to create a unified method for both QJM's Paxos dir and FJM.
