What do folks think?
Not putting the log into hdfs seems like a good idea.
I was somehow thinking the opposite as it makes irrecoverable machine
failures much more problematic. What makes you say it's a good idea?
Allows more control over the write path, specifically sequential I/O and
crash recovery. Granted the commit needs to be replicated, but you need
that regardless. Thinking a bit more it might not square with the
regionserver model anyway, plus the Accumulo proposal mentions a service
rather than a local disk. The WAL seems to be hardened up these days
anyway making things like
https://issues.apache.org/jira/browse/HBASE-4107 more of an edge case..
