Installed 6.1.13 on CentOS 7 for HDP 2.5
In running Cluster Health tests, I get an error in spark.log
17/01/12 19:05:32 WARN Client: Failed to connect to server: 10.0.1.7/10.0.1.7:8030: retries get failed due to exceeded maximum allowed retries number: 50
java.net.ConnectException: Connection refused
Which I researched ot ipv6 enabled for YARN whch I disabled successfully, however, I am still unable to launch 10.0.1.7:8030 on browser to see if it works.
also did sudo sysctl -p to make the ipv4 settings take immediate effect which worked but diong netstat -aln | grep 8030 still showipv6
Any thoughts how to get past it?
