azure - Why does WebHCat give null values in JSON when querying HDInsight cluster? -


i using webhcat in example microsoft: https://docs.microsoft.com/en-us/azure/hdinsight/hdinsight-hadoop-use-hive-curl submit hive queries on hdinsight cluster in azure.

i have transformed curl code javascript. submitting job, checking status of job, , finding output.

when checking status of job via webhcat, there lot of keys returned in json format. 1 used check status of job status.state (this returns value like: 'prep', 'running', 'failed', 'succeeded').

there interesting key in json called percentcomplete. percentage value represents readiness of data very useful me, yet every time check json status, status does update, percentcomplete has value of null.

(also note, many of other keys in json have falsey values well).

does know why json returned webhcat has many values equal falsey or null values? there way fix this?
