Steve Loughran commented on HADOOP-12649:
-----------------------------------------
+ make {{"hadoop.kerberos.kinit.command"}} a string constant rather than a
string in UGI
> 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.
