Subject [jira] [Created] (HADOOP-8574) Enable starting hadoop services from inside OSGi
Date Fri, 06 Jul 2012 15:55:35 GMT
Guillaume Nodet created HADOOP-8574:

             Summary: Enable starting hadoop services from inside OSGi
                 Key: HADOOP-8574
                 URL: https://issues.apache.org/jira/browse/HADOOP-8574
             Project: Hadoop Common
          Issue Type: New Feature
            Reporter: Guillaume Nodet

This JIRA captures the needed things in order to start hadoop services in OSGi.

The main idea I used so far consists in:
  * using the OSGi ConfigAdmin to store the hadoop configuration
  * in that configuration, use a few boolean properties to determine which services should
be started (nameNode, dataNode ...)
  * expose a configured url handler so that the whole OSGi runtime can use urls in hdfs:/xxx
  * the use of an OSGi ManagedService means that when the configuration changes, the services
will be stopped and restarted with the new configuration
