clean_spark_worker_dir.rb fix

[wcawman]

apache_spark/templates/default/clean_spark_worker_dir.rb.erb

Line 76 in 6197fd4

JOB_DIR_RE = /^app-(\d{14})-\d{4}$/

Your latest release has the following:
JOB_DIR_RE = /^app-(\d{14})-\d{4}$/
But your master branch appears to have the correct configuration:
JOB_DIR_RE = /^app-(\d{14})-\d{4,}$/

Could you merge this correction into a released version, thanks!
