Lars Hofhansl commented on HBASE-5954:
--------------------------------------
Sigh... The WAL files would still need to be sync'ed upon blockclose. Since
they mix data from different stores, there's no telling ahead of time. Which
leads to:
# global hsync option upon close block for HFiles and Hlogs (makes no sense to
sync HLogs but not HFiles or vice versa)
# global WAL edit hsync option
# hsync CF's WAL edits
# WAL hsync per Put/Delete/Append/Increment/etc
> Allow proper fsync support for HBase
