I've setup a cluster using Hortonworks HDP with Ambari all running in AWS.
I then created a separate EC2 instance and installed PIO 0.12.1, hadoop,
elasticsearch, hbase, and spark2. I copied the configurations from the HDP
cluster and then pio-start-all. The pio-start-all completes successfully
and running "pio status" also shows success. I'm following the "Text
Classification Engine Tutorial". I've imported the data. I'm using the
following command to train: "pio train -- --master yarn". After running
the command I get the following exception. Does anyone have any ideas of
what I may have missed during my setup?
Thanks in advance.
