Zhe Zhang created HDFS-8302: ------------------------------- Summary: Consolidate log purging logic in QJM and FJM Key: HDFS-8302 URL: https://issues.apache.org/jira/browse/HDFS-8302 Project: Hadoop HDFS Issue Type: Improvement Reporter: Zhe Zhang Assignee: Zhe Zhang
When executing {{purgeLogsOlderThan}}, {{JNStorage}} purges both the current directory and the Paxos directory using its own logic: {code} void purgeDataOlderThan(long minTxIdToKeep) throws IOException { purgeMatching(sd.getCurrentDir(), CURRENT_DIR_PURGE_REGEXES, minTxIdToKeep); purgeMatching(getPaxosDir(), PAXOS_DIR_PURGE_REGEXES, minTxIdToKeep); } {code} Meanwhile, FJM has its own logic of serving {{purgeLogsOlderThan}}, which is executed only under the legacy NFS-based journaling configuration. This JIRA aims to consolidate these 2 separate purging procedures -- This message was sent by Atlassian JIRA (v6.3.4#6332)
