---------------------------------
Summary: Let Input/Output Processors load local xml configs
Key: TEZ-4141
URL: https://issues.apache.org/jira/browse/TEZ-4141
Project: Apache Tez
Issue Type: Improvement
Reporter: Mustafa Iman
Assignee: Mustafa Iman
We would like to reduce the amount of configuration going over the wire from a
client to application master. If Input/Output processors load local config
files, we can reduce the configuration overhead when client and the processors
have the exact same config on both sides. It is on user of client to keep the
configs same on both sides. Currently, clients have to send all config in
payload. Even if we preload config with local xml files, these should be
overridden by the full config object coming in payload. Therefore, old clients
that send all the config anyway would not be affected in terms of correctness
from this change.
