Subject Re: Container request with short hostname vs full hostname issue
Date Tue, 20 May 2014 01:54:17 GMT
To my understanding, resource manager(RM) only knows the current active
host by its "long" name; if a host is not seen, it will assume it is not
active NOW.
when RM sees a short name, it doesn't know this is a short name for some
long name so it will not assign it to any node; but instead it will wait
for some other hosts to register as the short name (which will not happen);
