Hi community, Does Hadoop 3.x provide wire compatibility between 3.x clients and 2.x server? There is a blog post from Cloudera [1] mentioning wire compatibility between 2.x clients and 3.x server, but not the other direction. Curious if someone knows this. Also it'd be good to know if someone is running this setup in prod. Thanks!
