So you are trying to start BigSQL on your mac and get the following error:
java <Error>: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged.
after trying to run the following command:
hadoop namenode -format
The issue may have to do with the combination of your OS and Java version (we saw the error with OS 10.7.4 and Java version 1.6.0_51). We fixed this issue by updating the version of Java to the latest release and changed the definition of JAVA_HOME in setENV.sh in the main BigSQL directory.
