Subject [jira] [Created] (HDFS-8304) Separate out shared log purging methods for QJM (Paxos directory) and FJM
Date Thu, 30 Apr 2015 18:33:06 GMT
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.
