-----------------------------------
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_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."
