Re: HDFS Installation / Configuration
Hi Yuvrajsinh

In hdfs the directory information exixts as metadata on the name node. The data is stored as hdfs blocks on datanodes.

You can list the created dir/files in hdfs using

hadoop fs -ls /

Subject: RE: HDFS Installation / Configuration

Dear Tariq,

All Web GUI are working fine. I can be able to make the directories using
./hadoop fs -mkdir command. (For Ex. ./hadoop fs -mkdir /test)
But where this files are getting created ? also the same directory created
on both the Node ?

I can see folder created on Namenode->Browse the filesystem Link. But the
same was not available on OS Level.

Sorry, But I am new in HDFS. So please excuse me for silly questions.

Hello Yuvrajsinh,

        Hadoop provides us web interfaces using which we can see the status
of our cluster to check if everything is ok. Simply point your web browser
to http://namenode_host:50070(for Hdfs status) and to
http://jobtracker_host:50030(for MapReduce status). Apart from this just
give a try to few basic shell commands to see if everything is going
fine(like bin/hadoop fs -ls /, bin/hadoop fs -mkdir /testdir etc). Also try
to run the wordcount program once.
