I want to use the cm api , check this job is still running or not running.

Steps：

1. Spark streaming job running is 2 days.

2. Shell：
   JOB_NAME=SparkStreamingJob
   curl -u $CDHUSER:$CDHPASSWORD $CDHURL/api/v17/clusters/JYDWCluster/services/yarn/yarnApplications > cdh.json
   cat cdh.json | grep -A 4 $JOB_NAME > job.log
   RUNNINGNUM=cat job.log | grep "state" | grep "RUNNING" | wc -l

3. In most cases, this job is existed in the cm api result.
   But ,once in a while, this job is not existed in the cm api result, is strange.
   I suspect it's a bug.
