> This patch introduces config merging to various Input and Output processors.
> As described in https://issues.apache.org/jira/browse/TEZ-4073 , we need to
> reduce the size of the configuration objects transferred over the wire. There
> are two improvements we are planning to do regarding to that:
> # Skip sending default configs and configuration coming from xml files in
> payload
> # Send dag, vertex and session configurations in layers instead of sending
> dag + vertex + session configs all together three times.
> In order to achieve these,
> * We need to expose local config coming from configuration files to
> TaskContext.
> * Input/Output processors must merge the config from user payload to local
> config in their TaskContext
> This is the configuration merging part. After this is merged, corresponding
> changes should be made on Hive side to prevent sending redundant configs.
> Until Hive side is updated, changes here are only overhead because all the
> config objects are the same and they have all the config options anyway.
