------------------------------
Summary: Support combining orc files in Hadoop streaming
Key: ORC-430
URL: https://issues.apache.org/jira/browse/ORC-430
Project: ORC
Issue Type: Improvement
Reporter: Yuanbo Liu
In the case of huge number of orc files, there seems no CombineOrcFile class
existing to decrease mappers. When we use hadoop streaming in such case,
hadoop cluster will apply a lot of mappers. It would be great that we can
combine a batch of orc files into one mapper.
