             Summary: Add support for logaggregation to a path on non-default filecontext
                 Key: YARN-2137
                 URL: https://issues.apache.org/jira/browse/YARN-2137
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: log-aggregation
    Affects Versions: 2.4.0
            Reporter: Sumit Kumar


Current log-aggregation implementation supports logaggregation to default filecontext only. This patch is to support logaggregation to any of the supported filesystems within hadoop eco-system (hdfs, s3, swiftfs etc). So for example a customer could use hdfs as default filesystem but use s3 or swiftfs for logaggregation. Current implementation makes mixed usages of FileContext+AbstractFileSystem apis as well as FileSystem apis which is confusing.

This patch does two things:
# moves logaggregation implementation to use only FileContext apis
# adds support for doing log aggregation on non-default filesystem as well.
