[jira] [Created] (YUNIKORN-1550) pass k8s node labels as attributes not json

Wilfred Spiegelenburg created YUNIKORN-1550:
-----------------------------------------------

             Summary: pass k8s node labels as attributes not json
                 Key: YUNIKORN-1550
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-1550
             Project: Apache YuniKorn
          Issue Type: Bug
          Components: shim - kubernetes
    Affects Versions: 1.2.0
            Reporter: Wilfred Spiegelenburg


The k8shim in YUNIKORN-1389 was extended to pass on the K8s node labels to the core via the attributes. The K8s node labels are marshalled into a single json string. The string is added using a new key.

There are multiple issues with that. The overhead of un-marshalling it each time a label needs to be checked for existence is large. It also needs a two step check to find a label. First find the label in the attributes and then un-marshal the string and do another check for the real key & value needed.

We should add the labels from the K8s node as entries in the attributes map. Each label becomes and entry not json marshalling.
