Subject Spark Configuration of spark.worker.cleanup.appDataTtl
Date Tue, 16 Jun 2015 06:52:23 GMT
Hi guys:       I added a parameter "spark.worker.cleanup.appDataTtl   3 * 24 * 3600" in my
conf/spark-default.conf, then I start my spark cluster. However I got an exception:
15/06/16 14:25:14 INFO util.Utils: Successfully started service 'sparkWorker' on port 43344.

How to set this parameter correctly?       
BTW, I searched this property in http://spark.apache.org/docs/latest/configuration.html and
got no match. This property was found in http://spark.apache.org/docs/latest/spark-standalone.html
with a default value "7 * 24 * 3600 (7 days)", which I also tried but also failed.Thanks
