Work Description: sunchao commented on pull request #2611:
URL: https://github.com/apache/hadoop/pull/2611#issuecomment-812730610
> I think so. Previously people may include hadoop-common and expect
snappy/lz4 codec there. Where should we notify the people? release-note?
Perhaps we should create a page for compression codecs, under "Tools"
category of https://hadoop.apache.org/docs/current/index.html. This can be done
separately though after this is merged. We also need release notes I assume.
> You mean to let codec loader to report what codecs there are?
I think maybe some informative error message that users should have
`hadoop-compression` jar in their classpath or project dependencies, when the
class loader fail to find the codec class.
@steveloughran do you still think this is a worthwhile thing to do? and I
assume this targets Hadoop 3.4.x, not 3.3.x, is that correct?

> We added lz4-java, snappy-java dependencies to replace native libs. As per
> the suggestion from the review comments, we better add a hadoop module to
