Description

There are interests to backport HTTPFS back to Hadoop 1 branch. After the initial investigation, there're quite some changes in HDFS-2178, and several related patches, including:

HDFS-2284 Write Http access to HDFS
HDFS-2646 Hadoop HttpFS introduced 4 findbug warnings
HDFS-2649 eclipse:eclipse build fails for hadoop-hdfs-httpfs
HDFS-2657 TestHttpFSServer and TestServerWebApp are failing on trunk
HDFS-2658 HttpFS introduced 70 javadoc warnings

The most challenge of backporting is all these patches, including HDFS-2178 are for 2.X, which code base has been refactored a lot and quite different from 1.X, so it seems we have to backport the changes manually.
