Subject [jira] [Created] (HBASE-13129) Add troubleshooting hints around WAL retention from replciation
Date Sat, 28 Feb 2015 17:12:04 GMT
Sean Busbey created HBASE-13129:

             Summary: Add troubleshooting hints around WAL retention from replciation
                 Key: HBASE-13129
                 URL: https://issues.apache.org/jira/browse/HBASE-13129
             Project: HBase
          Issue Type: Improvement
          Components: documentation, Replication
            Reporter: Sean Busbey

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_17uOw@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."
