Description
I saw a situation where "accumulo init" exited with error code 255, the HDFS directories were successfully created, and security was not initialized. The contents of accumulo-init.out were the following. I realize no good can come of running init when there are no DataNodes, but it would be nice if init cleaned up after itself when it fails.
