Meantime, copy the file down from hdfs and pass it to the script (w/
the -f and -v flags)
I've copy the file from hdfs to my local machine.
but sorry! I don't know how to pass it to the script w/ the -f and -v
flags.
Could you give me a example.
Thank you very much

Looks like you need to pass -f so:
$ ./bin/hbase org.apache.hadoop.hbase.io.hfile.HFile -v -f
hdfs://x:9000/hbase/TestTable/efeb1bab2d99b205ec8837fc40d7010a/info/5319664235715793176
... but then you'll probably get this:
java.lang.IllegalArgumentException: Wrong FS.....
I'll fix this in TRUNK
Meantime, copy the file down from hdfs and pass it to the script (w/
the -f and -v flags).
