Running Dr.E version 2.0.6 
Spark version 2.1.0
CDH version 5.4.0
Kerberos enabled 
In the dr-elephant.log I am seeing 

ERROR [dr-el-executor-thread-0] com.linkedin.drelephant.spark.fetchers.SparkFetcher : Failed fetching data for application_N_N
java.util.concurrent.TimeoutException: Futures timed out after [30 seconds]

Also seeing a buildup of over 1300 jobs to analyze 
Eventually the analysis fails after 3 retries
