the release correspond to branch: v1.1-release, you can checkout the code.
the HadoopStatusChecker visits a URL which contains job status in json, and
parse the text to get the values. The pattern of URL is:
http(s)://${yarn.resourcemanager.webapp.address}/ws/v1/cluster/apps/${job_id}?anonymous=true
(check MapReduceExecutable:177)
My guess is that the text returned from your cluster's resource manager is
not as expected, which causes NPE in HadoopStatusGetter.java:56
can you check what is returned from the URL? for the real URL you can
either check backend log(in tomcat/log/kylin.log) or the log icon for each
cubing step.
