tip

Nginx does not handle websocket requests. Configure nginx proxy for websockets.

tip

Set larger socket timeout (or 0 to set no timeout).

tip

Upgrade your nanohttpd

tip

It takes too long time for the JVM to find enough entropy for secure connection. Use this jvm option: '-Djava.security.egd=file:/dev/./urandom'.

tip

Upgrade yokozuna

As Paul Socha pointed out, the workaround is to change the setup for your application, by adding this parameter to the java command: -Djava.security.egd=file:/dev/../dev/urandom This should be documented in the Sqoop User Guide.
