----------------------------------------
Summary: IBM Java classes should be excluded from relocation in
shaded Hadoop libraries
Key: HADOOP-17971
URL: https://issues.apache.org/jira/browse/HADOOP-17971
Project: Hadoop Common
Issue Type: Bug
Affects Versions: 3.3.1
Reporter: Nicholas Marion
IBM Java classes are shaded in Hadoop libraries, e.g. hadoop-client-api. When
loaded by Spark, UserGroupInformation has exception:
{noformat}
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

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