Hue Incompatible Changes

HUE-1658 [oozie] Hue depends on OOZIE-1306 which is in CDH 5 Beta 2 but has not been included in any other release yet. Set the following backward compatibility flag to false to use the old frequency number/unit representation instead of the new crontab.
```
enable_cron_scheduling = false
```
Hue 3.0.0 was a major revision of Hue. The user interface changed significantly.
CDH 5 Hue requires Python 2.6 and above, effectively dropping support for Python 2.4 and 2.5. Hue will install without Python 2.6, but will not start.
Note: RHEL 5 and CentOS 5 users will have to download Python 2.6 from the EPEL repository. See Installing Hue for instructions.
The Beeswax daemon has been replaced by HiveServer2. Hue should therefore point to a running HiveServer2. This change involves removing the Beeswaxd code entirely and the following major updates to the [beeswax] section of the Hue configuration file, hue.ini.
```
[beeswax]
  # Host where Hive server Thrift daemon is running.
  # If Kerberos security is enabled, use fully-qualified domain name (FQDN).
  ## hive_server_host=<FQDN of Hive Server>

  # Port where HiveServer2 Thrift server runs on.
  ## hive_server_port=10000
```
Search bind authentication is now used by default instead of direct bind. To revert to the previous settings, use the new search_bind_authentication configuration property.
```
[desktop]
[[ldap]]
search_bind_authentication=false
```
The Hue Shell app has been removed completely. This includes removing both the Shell app code and the [shell] section from hue.ini.
YARN should be used by default.
