On starting spark-shell I see this just before the scala prompt: WARN : Your hostname, BloomBear-SSD resolves to a loopback/non-reachable address: fe80:0:0:0:0:5efe:c0a8:317%net10, but we couldn't find any external IP address!
I get this error even when firewall is disabled. I also tried setting the environment variable SPARK_IP_LOCAL to various choices listed below: SPARK_LOCAL_IP=localhost SPARK_LOCAL_IP=127.0.0.1 SPARK_LOCAL_IP=192.168.1.88 (my local machine's IPv4 address) SPARK_LOCAL_IP=fe80::eda5:a1a7:be1e:13cb%14 (my local machine's IPv6 address) I still get this annoying error! How can I resolve this?
