Hi, when use "hadoop dfs -cat" command, I keep getting the problem that
says " Could not obtain block 0 from any node: java.io.IOException: No live
nodes contain current block"
The block does exist as the "cat" command didn't always fail, occasionally
it will return desired result, but most of time I just get that error.
I also checked with hadoop web console and find all data-nodes living.
I'm using hadoop 0.13.1, deployed on a cluster of 6 servers, all run on
AMD64 and OpenSuse 10.2 64X, with 2G RAM.
This problem happens only recently afterI imported a bulk of data(1G) into
HDFS.
Any idea how I can fix it? or will upgrade to 0.14.2 help?
Thanks
