----------------------------------------
Summary: Kerby breaks multiple SPN support
Key: HADOOP-14330
URL: https://issues.apache.org/jira/browse/HADOOP-14330
Project: Hadoop Common
Issue Type: Bug
Components: security
Affects Versions: 3.0.0-alpha1
Reporter: Wei-Chiu Chuang
Priority: Blocker
Hadoop 3 currently pulls in Kerby 1.0.0 RC2. Via downstream application tests,
we found a bug in this version that breaks multiple SPN support implemented in
HADOOP-10158, because Kerby can't read keytabs generated by some applications,
and it gets malformed SPNs. The bug is fixed by DIRKRB-621, targeting Kerby
1.0.0 GA release.
I also verified this regression is fixed in latest Kerby, by having my local
Hadoop repo depend on my local 1.0.0-RC3-SNAPSHOT Kerby artifacts. So the
easiest fix is to wait for a Kerby 1.0 RC3/GA, and update Hadoop pom.xml to
depend on Kerby 1.0 GA.
The planned alpha 3 release is approaching, so I don't anticipate this can get
resolved by then. Beta1 is probably a more realistic target version.
