----------------------------
Summary: Have MultiMROutput support different configurations for
different writers
Key: TEZ-3722
URL: https://issues.apache.org/jira/browse/TEZ-3722
Project: Apache Tez
Issue Type: Improvement
Reporter: Ming Ma
TEZ-3215 added the support for MultiMROutput so that a task can write its
output to different HDFS files depending on the data. Internally MultiMROutput
creates different writers keyed by the path. All writers use the same
configuration.
We have use cases that different writers need to have different configurations,
it can be used to specify different output formats, or different configuration
values for the same output format. So it will be useful to allow applications
to specify different configuration for different writers.
