Re: Fault Tolerancy in core hadoop and HDFS

You might also be interested in hadoop-lafs
(http://code.google.com/p/hadoop-lafs ) which lets Hadoop use
Tahoe-LAFS (http://tahoe-lafs.org ) instead of HDFS. Tahoe-LAFS is a
fault-tolerant distributed data store which uses erasure coding (c.f.
https://issues.apache.org/jira/browse/HDFS-503 ) and SHA-256-based
integrity checks.
