Namenode has non-empty /hadoop/dfs/name and not formatting #50

Open choralqiu opened 6 years ago

choralqiu commented 6 years ago

In HA mode, namenode will error out because /hadoop/dfs/name is not empty and can't be formatted in non-interactive mode. This will error out the namenode.

Some extra info/observations:

  1. I'm on uber-chart branch with commit on aef9586ecc8551ca0f0a468c3b917d8c38f494a0
  2. I spin-up the cluster overnight, the namenode issue went away when I checked it in the morning. That's about 10 hours. Then the datanode can't connect to the namenode.
  3. I did wait for journal nodes and zookeeper nodes to come up. And waited for about 45 mins.
  4. I was using helm install -n my-hdfs charts/hdfs-k8s to spin things up.
  5. I'm not on the default namespace.
  6. Here's the log on namenode-0 
    yqiu-mac:~ yqiu$ kubectl logs -f my-hdfs-namenode-0
