Distcp between Hadoop 2.6 ( CDH 5.16.2 ) and Haddop 3.0 ( CDH 6.3.2 )

Expert Contributor

Hello,

 

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.

https://hadoop.apache.org/docs/r3.0.3/hadoop-distcp/DistCp.html#Copying_Between_Versions_of_HDFS

 

Can you give me some comment for this?

 

Thank you very much in advance.
