I’m running up against this issue w/ Mesos 0.19 and Spark 1.0.1 - https://www.mail-archive.com/issues@spark.apache.org/msg06732.html
Caused by: javax.security.auth.login.LoginException: unable to find LoginModule class: org/apache/hadoop/security/UserGroupInformation$HadoopLoginModule Any clues of where to look?
