Subject [jira] [Commented] (HDFS-8201) Add an end to end test for stripping file writing and reading

Zhe Zhang commented on HDFS-8201:

Thanks for working on this Xinwei!

Not sure if you have noticed, {{TestDFSStripedInputStream}} was added as part of HDFS-8136.
It looks quite similar to this patch. Maybe we should cleanup and optimize that test under
this JIRA?

> 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.
