stack commented on HBASE-15265:
-------------------------------
Needs a release note when you get a chance [~Apache9]
Why is this option called asyncfs and not something like async_wal?
I set this in my config:
<property>
<name>hbase.wal.provider</name>
<value>asyncfs</value>
</property>
<property>
... but don't seem to see anything in logs saying async wal is enabled.... What
do you see?
I have this:
{code}
2016-03-09 22:26:04,968 INFO
[regionserver/ve0530.halxg.cloudera.com/10.17.240.23:16020] wal.AbstractFSWAL:
WAL configuration: blocksize=128 MB, rollsize=121.60 MB,
prefix=ve0530.halxg.cloudera.com%2C16020%2C1457591160305, suffix=,
logDir=hdfs://ve0524.halxg.cloudera.com:8020/hbase/WALs/ve0530.halxg.cloudera.com,16020,1457591160305,
archiveDir=hdfs://ve0524.halxg.cloudera.com:8020/hbase/oldWALs

{code}
.... does this mean async WAL is 'on'?
