binlijin created HBASE-18309: -------------------------------- Summary: Support multi threads to clean oldWALs Key: HBASE-18309 URL: https://issues.apache.org/jira/browse/HBASE-18309 Project: HBase Issue Type: Improvement Reporter: binlijin
There is only one thread in LogCleaner to clean oldWALs and in our big cluster we find this is not enough. The number of files under oldWALs reach the max-directory-items limit of HDFS and cause region server crash, so we use multi threads for LogCleaner and the crash not happened any more. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
