Turning off the banner

By default, Blazegraph starts with a large wall of text:

BlazeGraph(TM) Graph Engine

                   Flexible
                   Reliable
                  Affordable
      Web-Scale Computing for the Enterprise

[...]

To turn off the banner, using the blazegraph.properties file is not sufficient. Instead, you have to either provide a VM argument (-Dcom.bigdata.Banner.quiet=true) or set it manually from code before instantiating Blazegraph's classes:

System.getProperties().setProperty("com.bigdata.Banner.quiet", "true");

This way, the banner is not displayed, but there is still another log message:

INFO: com.bigdata.util.config.LogUtil: Configure: file:/.../log4j.properties

To turn this off, set the LogUtil to quiet with another VM argument (-Dcom.bigdata.util.config.LogUtil.quiet=true) or from code:

System.getProperties().setProperty("com.bigdata.util.config.LogUtil.quiet", "true");
