I am trying to run HBase on Ubuntu. I've installed it and can start it (it throws some warning because I'm using a 64-bit system but I'm told I can ignore these). However, when I try to start the shell I get the error messages below, but I'm new to this so am struggling to figure it out. It says that Zookeeper exists but has failed 4 times - do you know why?
