There is sometimes an error while getting job status :

2018-05-18 08:29:46,557 [pool-5-thread-1] ERROR [com.bluebreezecf.tools.sparkjobserver.api.SparkJobServerClientImpl] - Error occurs when trying to get information of the target job:

Here is the final result from JobServer. There must be a transient satet where the result is not filled.
