Description

Zeppelin web UI very slow to respond on macOS Catalina.

Version: 0.9.0-preview2

Opening any page can take 0.5-2 minutes to load - index, notebook or interface configuration.

I looked at jstack for zeppelin process and it seems to be spending a lot of time in java.net.InetAddress.getLocalHost, as part of org.apache.zeppelin.server.CorsFilter.doFilter.

This Stackoverflow post mentions a similar issue on macOS and a workaround, which worked for me. After adding my hostname to the hosts file as described, zeppelin responds normally.

Possibly related to ZEPPELIN-2948
