Haohui Mai reopened HADOOP-8719:
--------------------------------
Reopen this issue since it breaks secure set ups running under Mac OS X. Secure cluster won't be able to start with null realm.
I propose to revert this patch.

> When starting Hadoop on OS X 10.7 ("Lion") using start-all.sh, Hadoop logs the following errors:
> 2011-07-28 11:45:31.469 java[77427:1a03] Unable to load realm info from SCDynamicStore
> Hadoop does seem to function properly despite this.
> The workaround takes only 10 minutes.
> There are numerous discussions about this:
> google "Unable to load realm mapping info from SCDynamicStore" returns 1770 hits. Each one has many discussions.
> Assume each discussion take only 5 minute, a 10-minute fix can save ~150 hours. This does not count much search of this issue and its solution/workaround, which can easily hit (wasted) thousands of hours!!!
