How to run zeppelin notebook from command line (automatically)

Question

1. How do we run the notebook from command line?

2. Further to 1, how would I pass command line arguments into the notebook? I.e. access the command line

Answer 1

So I had the same issue and managed to work out how to use the API to run a notebook using curl. As for passing in command line arguments think there is simply no way to do that - you will have to use some sort of shared state on the server (e.g. have the notebook read from a file, and modify the file).

Anyway this is how I managed to run a notebook, it assumes jq is installed. Pretty involved :(

curl -XGET http://${ip}:8080/api/interpreter/setting | jq '.body[] | .id'

interpreter_settings_ids=`curl -XGET http://${ip}:8080/api/interpreter/setting | jq '.body[] | .id'`

id_array="["`echo ${interpreter_settings_ids} | tr ' ' ','`"]"

curl -XPUT -d $id_array http://${ip}:8080/api/notebook/interpreter/bind/${notebook_id}

curl -XPOST http://${ip}:8080/api/notebook/job/${notebook_id}

If someone has manually clicked the "save" button for the interpreter binding then only the last command is required.

UPDATE:

OK I think you can loop to probe the status of the running notebook to determine if the notebook failed, see: https://github.com/eBay/Zeppelin/blob/master/docs/rest-api/rest-notebook.md

For example

function job_success {
    num_cells=`curl -XGET http://${ip}:8080/api/notebook/job/${notebook_id} 2>/dev/null | jq '.body[] | .status' | wc -l`
    num_successes=`curl -XGET http://${ip}:8080/api/notebook/job/${notebook_id} 2>/dev/null | jq '.body[] | .status' | grep FINISHED | wc -l`
    test ${num_cells} = ${num_successes}
}

function job_fail {
    curl -XGET http://${ip}:8080/api/notebook/job/${notebook_id} 2>/dev/null | jq '.body[] | .status' | grep ERROR
}

until job_success || job_fail
do
    sleep 10
done

As of version 0.7.3 and perhaps earlier, Zeppelin has a REST API that lets you run notebooks. Your shell script can use curl to access the API.

The API includes methods to delete a paragraph and to insert a paragraph at a particular index. This allows you to express all your "parameters" as variables in paragraph 0 and then use them in later paragraphs. Make 3 calls to the REST API in this order:

1. Delete the notebook's current paragraph 0.
2. Insert a new paragraph containing variable assignments at index 0.
3. Run the notebook.
