Mac(Mojave). Standalone quits. Failed to start pulsar service.

Describe the bug Hi, When I run bin/pulsar standalone it quits.

To Reproduce Steps to reproduce the behavior:

wget https://archive.apache.org/dist/pulsar/pulsar-2.4.1/apache-pulsar-2.4.1-bin.tar.gz
wget https://archive.apache.org/dist/pulsar/pulsar-2.4.1/connectors/pulsar-io-kafka-connect-adaptor-2.4.1.nar
tar zxf apache-pulsar-2.4.1-bin.tar.gz && cd apache-pulsar-2.4.1 && mkdir connectors && cp ../pulsar-io-kafka-connect-adaptor-2.4.1.nar connectors
bin/pulsar standalone

Expected behavior I expected it to continue to run

Desktop (please complete the following information):

• OS: MacOS(Mojave)

Additional context The error dump is in error.txt. My etc/hosts file just in case

# Host Database

# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.

[RAbraham]

the off chance, someone else has the same issue. I resolved it by:

• moving to openjdk8(may not be required. but it exposed the issue with a better error message than the default mac java 8, I think)
• add 127.0.0.1 <laptop name>.local to /etc/hosts or whatever name it errors out on your laptop
• dscacheutil -flushcache

Thanks @RAbraham ! For me, it works only with the 3 steps (with openjdk8).
