Rakesh R commented on HDFS-11416:

Thanks [~andrew.wang] for the patch. I've few minor comments,
# Please add javadoc for the newly added fnction {{StringUtils#byteToHexString(byte b)}}
# Please include fail statement for the test case {{TestStripedINodeFile#testInvalidECPolicy}}
      fail("Should throw IllegalArgumentException on invalid ec policy!");
    } catch (IllegalArgumentException e) {
      GenericTestUtils.assertExceptionContains("Could not find EC policy with" +
          " ID 0xbb", e);

>             Project: Hadoop HDFS
>          Issue Type: Improvement
>          Components: erasure-coding
>    Affects Versions: 3.0.0-alpha1
>            Reporter: Andrew Wang
>            Assignee: Andrew Wang
>              Labels: hdfs-ec-3.0-nice-to-have

> As discussed on HDFS-7859, the system default EC policy is mostly a relic from development
when the system only supported a single global policy. Now, we support multiple policies,
and the system default policy is mostly used by tests.
> We should refactor to remove this concept.
