> Should be able to do something similar to what we do for HDFS encryption.
> TestErasureCodingHDFSCliDriver uses a test-only CommandProcessor "ErasureProcessor"
> which allows .q files to contain Erasure Coding commands similar to those provided
> by the hdfs ec command
> The Erasure Coding functionality is exposed through a new shim "HdfsFileErasureCodingPolicy".
> At this stage there are two .q files:
> erasure_commnds.q (a simple test to show ERASURE commands can run on local fs via
> TestCliDriver or on hdfs via TestErasureCodingHDFSCliDriver), and
> erasure_simple.q (which does some trivial queries to demonstrate basic functionality).
> More tests will come in future commits.
