    @StephanEwen , when I run the YARNHighAvailabilityITCase, occur the following error. I set the flie /etc/hosts as following:
    9.96.101.32 9-96-101-32 
    127.0.0.1 localhost
    
    The hadoop version I use is master default version 2.7.0. Do you know how to fix the following error?Thanks a lot in advance!
