GitHub Commit Date (YYYY-MM-DD) Comment
5a7c872 2015-10-20 MAPR-21019: When Hue submits Oozie jobs, Hue uses the default_jobtracker_host value (maprfs:/// ) instead of the jobtracker host:port address.
5f7812d 2015-09-15 MAPR-20441: Hue now automatically detects the Sqoop security settings and Hue.ini no longer contains the sqoop_conf_dir property.
569dbf5 2015-09-15 MAPR-20438: Hue is now able to connect to the ResourceManager on secure cluster because the path to ssl_cacerts in the hue.ini was corrected.

ecdd711 2015-09-07 MAPR-20440: Hue now automatically detects the Hive security mechanism and therefore hive action statements in Oozie workflows no longer fail.
