Subject [jira] [Commented] (HBASE-15536) Make AsyncFSWAL as our default WAL
Date Thu, 20 Oct 2016 17:34:59 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15536?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15592441#comment-15592441

stack commented on HBASE-15536:
-------------------------------

I could do test again, np. Nice digging [~ram_krish]. Am in here myself looking at dfsclient
at mo (which makes me wish the more for asyncfswal.... smile).

Looking at the release note, it is missing mention of the limitations of asyncwal -- i.e.
that maximum size is 16M. Need to add that too. Or rather, lets test what happens when too-big
load. Let me help here.
