Subject Wire compatibility between Hadoop 3.x client and 2.x server
Date Mon, 12 Oct 2020 22:41:05 GMT
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!

Chao
