Misty Stanley-Jones updated HBASE-13129: ---------------------------------------- Attachment: HBASE-13129.patch Ready for review. > Add troubleshooting hints around WAL retention from replication > --------------------------------------------------------------- > > Key: HBASE-13129 > URL: https://issues.apache.org/jira/browse/HBASE-13129 > Project: HBase > Issue Type: Improvement > Components: documentation, Replication > Reporter: Sean Busbey > Assignee: Misty Stanley-Jones > Labels: operations, supportability > Attachments: HBASE-13129.patch > > > There's been some confusion on the mailing list about when WALs get retained > / cleaned up once replication is on at all in a cluster. (ref [this > thread|http://mail-archives.apache.org/mod_mbox/hbase-user/201502.mbox/%3ccamuu0w9aovbo7kgulim9txrulirqs9fm-3ra3pqccypw_17...@mail.gmail.com%3E]) > We should add a NOTE in the replication section that wals are saved across > enable/disable so long as there are peers. There looks like there might also > be some confusing language around replication being enabled in the configs vs > the enable/disable suspension mechanism. > We should also add a troubleshooting item specific for "my HDFS space keeps > growing and it's all in oldWALs." -- This message was sent by Atlassian JIRA (v6.3.4#6332)
