WSO2 Storage Server ships preconfigured HDFS file system. In the default configuration HDFS is disabled and user has to enable it by disabling the system variable named disable.hdfs.startup in $SS_HOME/bin/wso2server.sh.

enable.hdfs.startup=true

HDFS Name Node

To start HDFS name node, open a command prompt (in Windows) or a text Linux console (in Linux) in $SS_HOME/bin directory and execute wso2server.bat (in Windows) or wso2server.sh (in Linux). 

HDFS Data Node 

Do not format a running Hadoop file system, this will cause all your data to be erased. Before formatting, ensure that the dfs.name.dir directory exists. The name node can be formatted by running the following command from the /wso2ss-1.1.0/bin location.

./hadoop namenode -format

To start the HDFS data node, change the directory to $SS_HOME.

HADOOP_SECURE_DN_USER=<user> sudo -E bin/hadoop datanode
 
The user should have sudo privileges.
