---------------------------------

HDFS-8202 was also opened to improve the test for erasure recovering.

> According to off-line discussion with [~zhz] and [~xinwei], we need to implement an end
to end test for stripping file support:
> * Create an EC zone;
> * Create a file in the zone;
> * Write various typical sizes of content to the file, each size maybe a test method;
> * Read the written content back;
> * Compare the written content and read content to ensure it's good;
> The test facility is subject to add more steps for erasure encoding and recovering. Will
open separate issue for it.
