Lars Hofhansl commented on HBASE-5954:
--------------------------------------
I almost feel like the HFile sync should be enabled by default. This ensures
that after an HFile is written and closed all of its blocks are sync'ed to
disk. The overhead of this is "fairly" minimal.
The edit-by-edit sync for the WAL is definitely optional.
> Allow proper fsync support for HBase
