Re: Corrupt HFile

Which version of Hadoop?
If you get a data center wide power outage you can lose data.

In Hadoop 1.1.1 or later you force a sync on block close, and thus you won't at least lose any old data (i.e. HFiles that were recently written due to compactions).

I have blogged about that here:

We use hbase-0.94.10 and encounter corrupt hfile.
