stack commented on HBASE-10156:
-------------------------------
bq. What are you seeing lads? Ain't this doing same as 0.98 did; i.e. sync and
not return until sync completes? Or you seeing double sync call per meta write?
I see now. Should be: "doSync && info.isMetaRegion()" instead of "doSync ||
info.isMetaRegion()"
Just removing "!htd.isDeferredLogFlush()" and parens ended up adding a sync.
Good one.
What you seeing? Slow down?
