Summary: Improve UGI diagnostics and failure handling Key: HADOOP-12649 URL: https://issues.apache.org/jira/browse/HADOOP-12649 Project: Hadoop Common Issue Type: Improvement Components: security Affects Versions: 2.7.1 Environment: Kerberos Reporter: Steve Loughran Sometimes —apparently— some people cannot get kerberos to work. The ability to diagnose problems here is hampered by some aspects of UGI # the only way to turn on JAAS debug information is through an env var, not within the JVM # failures are potentially underlogged # exceptions raised are generic IOEs, so can't be trapped and filtered # failure handling on the TGT renewer thread is nonexistent # the code is barely-readable, underdocumented mess. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
