Subject [jira] [Commented] (YARN-2137) Add support for logaggregation to a path on non-default filecontext
Date Mon, 04 May 2015 23:07:07 GMT

Xuan Gong commented on YARN-2137:

[~ksumit] I think that https://issues.apache.org/jira/browse/YARN-3269 might be duplicate
for this issue.

> 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
