Hemanth Yamijala updated HADOOP-3479:
-------------------------------------
Attachment: 3479.patch
The attached patch is a work-in-progress version of the resource manager
configuration changes following requirements in HADOOP-3421. It is incomplete
and only intended to get some early feedback on the basic approach.
The following changes are included:
- Introduced a *resource-manager-conf.xml* which will be the basic
configuration file for all resource manager related configuration. By default
it ships with one default queue. The values for the parameters in this queue
may need to be relooked and decided carefully.
- Introduced a *hadoop.resource-manager.config* variable in hadoop-default.xml.
User can specify a name of a file for this variable.
- Introduced a *ResourceManagerConf* class which is responsible for parsing the
config file and exposing the configuration through basic APIs. The main APIs
are:
{code}
Set<String> getQueues();
String get(String queueName, String propertyName);
{code}
There are convenience APIs for getting integers, booleans etc. More could be
added.
- The ResoureManagerConf reads from either the value specified in
hadoop.resource-manager.config if defined, or from the
resource-manager-conf.xml if the former is undefined.
- The ResourceManagerConf object is initialized from the JobTracker constructor
and exposed with a getter method. For illustration, I've just printed some LOG
messages printing the queues and the properties.
Unit tests, documentation and even API set need to be completed before the
patch can be submitted. If anyone feels strongly on an alternative approach,
please comment now.
