Slight hijack of the thread but how does one change the balancer role to another host? I wish to decommission the one that it is currently assigned to.

Sorry to drag up an old topic but I am hoping there is now some official guidance from Cloudera - or perhaps a reference architecture. As soon as an organisation builds a Cloudera EDH cluster in one Amazon AWS region (or Azure or Google Cloud, or whatever) then they soon realise they might want another cluster in a different region or a different Availability Zone. Personally I am happy sticking with one Region but multiple AZs - so I am thinking that I want one Cloudera Director, one Cloudera Manager, and separate clusters in each AZ.

Guru Medasani, a Solutions Architect here at Cloudera, has been able to use this technique to add EBS volumes to new instances, and he added additional commands to format the drives and mount them. Here's an extension to the script above that handles those tasks, based on his work. He used a Red Hat Enterprise Linux 7.2 AMI (ami-2051294a), so the commands for other operating systems or versions may vary. # Create filesystems on the devices
mkfs.xfs /dev/xvdf
mkfs.xfs /dev/xvdg
# Create directories for the mount points mkdir /data1 mkdir /data2
# Add the mount points to /etc/fstab
echo "/dev/xvdf /data1 xfs defaults,noatime 0 0" >> /etc/fstab
echo "/dev/xvdg /data2 xfs defaults,noatime 0 0" >> /etc/fstab
sleep 10
# Mount all the devices
mount -a
