Subject Fwd: HDFS: file is not distributed after upload
Date Fri, 07 Feb 2014 08:41:07 GMT
Hi, folks!

I've deployed hadoop (0.20.203.0rc1) on 8-node cluster. After uploading
file onto hdfs I've got this file only on one of the nodes instead of being
uniformly distributed across all nodes. What can be the issue?

$HADOOP_HOME/bin/hadoop dfs -copyFromLocal ../data/rmat-20.0
/user/frolo/input/rmat-20.0

$HADOOP_HOME/bin/hadoop dfs -stat "%b %o %r %n" /user/frolo/input/rmat-*
1220222968 67108864 1 rmat-20.0
