Steven Willis commented on ZOOKEEPER-1422: ------------------------------------------ [~phunt], I believe the functionality in HADOOP-8381 was what [~thw] was referencing. However, last time I checked, (which was a while ago) this functionality was not available in the zookeeper jaas configuration, only in the hadoop '*-site.xml' configuration files. Did the change introduced in HADOOP-8381 make the _HOST substitution more widely available? > Support _HOST substitution in JAAS configuration > ------------------------------------------------- > > Key: ZOOKEEPER-1422 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1422 > Project: ZooKeeper > Issue Type: Improvement > Affects Versions: 3.4.0 > Reporter: Thomas Weise > > At the moment a JAAS configuration file needs to be created with the Kerberos > principal specified as user/host. It would be much easier for deployment > automation if the host portion could be resolved at startup time, as > supported in Hadoop (something like user/_HOST instead of user/hostname). A > configuration alternative to global JAAS conf would be even better (via > direct properties in zoo.cfg?). -- This message was sent by Atlassian JIRA (v6.2#6252)
