Hi hadoop. I recently ran a spark job that uses the hadoop.security libraries for login (spark context does this)...
It threw an exception: java.io.IOException: failure to login at org.apache.hadoop.security.UserGroupInformation.getLoginUser(UserGroupInformation.java:700) at org.apache.hadoop.security.UserGroupInformation.getCurrentUser(UserGroupInformation.java:571) at org.apache.spark.util.Utils$$anonfun$getCurrentUserName$1.apply(Utils.scala:2181) at org.apache.spark.util.Utils$$anonfun$getCurrentUserName$1.apply(Utils.scala:2181) at scala.Option.getOrElse(Option.scala:120) And the root exception was: Caused by: javax.security.auth.login.LoginException: java.lang.NullPointerException: invalid null input: name This is running in a docker container. Is there anything in particular I need to do to run such containers (i.e. do we have a privileged requirement for UserGrouInfo or anything like that?)... -- jay vyas
