Thank you for reading this question.
Recently, one of Hadoop clusters we have has been upgraded to Hadoop 3.0 ( CDH 6.3.2 ).
I'm curious that the copied data from Hadoop 3.0 ( by distcp ) can be used by Hadoop 2.6 cluster.
I was able to distcp from Hadoop 3.0 cluster to Hadoop 2.6, but I found out this document.
Can you give me some comment for this?
Thank you very much in advance.
❏ Preserves compatibility with Hadoop 2 clients
❏ Distcp/WebHDFS compatibility preserved
