I asked a question yesterday about increasing disk capacity on my cluster in Ambari. After lots and lots of reading, I think I didn't ask the question correctly.
To start, I'm getting several warnings that I'm running out of HDFS disk:
Since I'm on a virtualized GCP environment, I just changed the disk capacities from 10 to 20 Gb on my 4 VMs.
Then I went into the CLI on each node and ran df -h
Obviously, I don't see the extra capacity I added since it's not been mounted, but this is where I get confused.
Looking at this thread:
I should create a directory at / and another in /home, point one to the other, change ownership and permissions, and then mount it.
But reading this thread:
I just need to create a directory, tell Ambari where that directory is under HDFS --> Configs (tab) --> DataNode box and restart the cluster.
Problem is, I've tried both methods and neither seem to be working for me. What am I doing wrong?
