Starting with Hadoop – 3

I was having too much problem with SELinux while trying to run the generic Hadoop distribution on Fedora.

I decided to install the prepackaged one with yum.

• sudo yum install hadoop-common hadoop-common-native hadoop-mapreduce

I was then able to start the different components with:

• sudo start-dfs.sh
• sudo start-yarn.sh

Now time to see if I can submit jobs to Hadoop.

To copy some file into HDFS:

hadoop fs -copyFromLocal ./sample.html hdfs://localhost:8020/
