Lars Hofhansl commented on HBASE-6962:
--------------------------------------
While 0.94 can be build against Hadoop 1.1.0 the behavior will be the same.
There is a lot of confusion about append, sync, hsync, hflush. Let me try to
clarify.
# HBase never needed append, but only the sync part of the 0.20 append branch.
# Until HDFS-744 Hadoop did not have any durable sync. hsync was identical to
hflush
# When we talk about sync in HBase we always mean hflush (until HBASE-5954 is
done, that is)
That means as far as this issue is concerned, you can safely switch to Hadoop
1.1.0.
