Subject Re: Checksum of blocks
Date Mon, 02 Aug 2010 03:18:29 GMT
Hi,

There is a method getChecksumFile(Path file)  that gives this info.
You could refer the javadoc here:
http://hadoop.apache.org/common/docs/current/api/org/apache/hadoop/fs/ChecksumFileSystem.html

Hope this helped.

Regards,
Krishnakumar.
