Varun Vasudev commented on YARN-2137:
-------------------------------------
No sorry. I should have been more clear.
http://hadoop.apache.org/docs/r2.3.0/hadoop-yarn/hadoop-yarn-site/YarnCommands.html#logs
- the "yarn logs" command is used to dump the logs that you aggregate on the
remote log dir. Have you confirmed that it uses the right FileContext?
> 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
> Attachments: YARN-2137.patch

>
> 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.
> # changes TestLogAggregationService to use local filesystem itself instead of
> mocking the behavior
