As p= art of that change, we also modified the NN RPC port from the famous 8020 t= o 9820, to be closer to other ports changed there. > With more integration going on, it appears that all the other ephemeral p= ort changes are fine, but the NN RPC port change is painful for downstream = on migrating to Hadoop 3. Some examples include: > # Hive table locations pointing to hdfs://nn:port/dir > # Downstream minicluster unit tests that assumed 8020 > # Oozie workflows / downstream scripts that used 8020 > This isn't a problem for HA URLs, since that does not include the port nu= mber. But considering the downstream impact, instead of requiring all of th= em change their stuff, it would be a way better experience to leave the NN = port unchanged. This will benefit Hadoop 3 adoption and ease unnecessary up= grade burdens. > It is of course incompatible, but giving 3.0.0 is just out, IMO it worths= to switch the port back. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: hdfs-issues-help@hadoop.apache.org
