I am new when it comes to upgrading hadoop components from source.
I am wondering if there are any compatibility issues when upgrading from source.
For example my current HDFS version is 2.7.3.
If I were to upgrade to the newest version of HDFS from source, I am wondering if there will be any incompatibility issues. Also is it possible to do rolling upgrades or would I need to schedule a maintenance window to upgrade the hadoop cluster from source.
Can someone please also help redirect me to where I can find more information on which versions of each of the hadoop components that I can upgrade my hadoop cluster with?
