Description

IBM Java classes are shaded in Hadoop libraries, e.g. hadoop-client-api. When loaded by Spark, UserGroupInformation has exception:

org.apache.hadoop.security.KerberosAuthException: failure to login: javax.security.auth.login.LoginException: unable to find LoginModule class: org.apache.hadoop.shaded.com.ibm.security.auth.module.JAASLoginModule
	at org.apache.hadoop.security.UserGroupInformation.doSubjectLogin(UserGroupInformation.java:1986)
	at org.apache.hadoop.security.UserGroupInformation.createLoginUser(UserGroupInformation.java:719)
	at org.apache.hadoop.security.UserGroupInformation.getLoginUser(UserGroupInformation.java:669)
	at org.apache.hadoop.security.UserGroupInformation.getCurrentUser(UserGroupInformation.java:579)
	at org.apache.spark.util.Utils$.$anonfun$getCurrentUserName$1(Utils.scala:2609)
	at org.apache.spark.util.Utils$$$Lambda$1388/0x00000000338e9c30.apply(Unknown Source)
	at scala.Option.getOrElse(Option.scala:189)

When I manually compile UserGroupInformation.java without maven (aka relocation) and inject the class files into hadoop-client-api jar; it works.
