This View provides a UI to browse HDFS, create directories and upload + download files.
The view can be built as a maven project.
mvn clean install
The build will produce the view archive.
target/files-0.1.0-SNAPSHOT.jar
Place the view archive on the Ambari Server and restart to deploy.
cp files-0.1.0-SNAPSHOT.jar /var/lib/ambari-server/resources/views/ ambari-server restart
Configure HDFS for a proxy user. In core-site.xml, add the following properties:
hadoop.proxyuser.root.hosts=* hadoop.proxyuser.root.groups=*
Create Hadoop users and make members of the hdfs, hadoop and users groups. For example, to create a user “admin”:
useradd -G hdfs admin usermod -a -G users admin usermod -a -G hadoop admin
Check the “admin” user has the correct group membership.
id admin uid=1002(admin) gid=1002(admin) groups=1002(admin),100(users),503(hadoop),498(hdfs)
Use the Ambari Vagrant setup to create a cluster:
Deploy the Files view into Ambari.
cp files-0.1.0-SNAPSHOT.jar /var/lib/ambari-server/resources/views/ ambari-server restart
From the Ambari Administration interface, create a Files view instance.

After deploying the view into a Vagrant VM, if you want to perform view development from your local build, perform the following:
Browse to the work directory.
cd /var/lib/ambari-server/resources/views/work
Remove the FILES{0.1.0} directory.
rm FILES\{0.1.0\}
Create a link to your local build.
ln -s /vagrant/ambari/contrib/views/files/target/classes/ FILES\{0.1.0\}
Restart Ambari Server.
ambari-server restart
