Subject Re: how to check hdfs
Date Tue, 03 Mar 2015 17:16:29 GMT
I use command
./hdfs dfs -ls hdfs://master:9000/
It works. So i think hdfs://master:9000/ should be the hdfs.

I have another questions, if
./hdfs dfs -mkdir hdfs://master:9000/directory
where should the /directory be stored?
In DataNode or in NameNode? or in the local system of master?
