I am running HDP Sandbox in an Azure VM. I can successfully add a disk to the VM and format / mount it. I would like to add it to HDFS to extend my storage. I am performing the following steps to get it recognized:
Create directory on the volume: i.e. mkdir
/data/hdfs/data
Change perms: sudo chmod -R
755 /data/hdfs/data
Change ownership: sudo chown
-R hadoop:hdfs /data/hdfs/data
Stop datanode through Ambari
Change dfs.data.dir property
in /etc/hadoop/conf/hdfs-site.xml, add directory comma delimited
Restart datanode Unfortunately, everytime I restart the datanode, the dfs.data.dir property reverts back to default. What am I doing wrong?
