Eric Wohlstadter updated TEZ-4014:
----------------------------------
Description:
When launching DAGAppMaster independently, clients won't have to chance
localize the configuration for DAGAppMaster in the protobuf format.
In these cases it is more convenient for a platform to provide an AM
configuration as plaintext.
This Jira adds util methods to load tez-site.xml and
service_plugins_descriptor.json from the classpath.
Some changes are made to the plugin descriptor classes to make them compatible
with jackson.
These util methods are unused in this Jira (execpt by tests). In another JIRA,
they will get plugged into DAGAppMaster.
was:
When launching DAGAppMaster independently, clients won't have to chance
localize the configuration for DAGAppMaster in the protobuf format.
In these cases it is more convenient for a platform to provide an AM
configuration as plaintext.
The change here will be to look for the protobuf conf first, and then fall back
to:
# Looking for a tez-site.xml text file in the classpath
# Looking for a service_plugins_descriptor in JSON format.
> Allow DAGAppMaster to read configuration from plaintext
