> All YARN/MapReduce components failed to start on 2.0.6.GlusterFS stack (on 
> HDP 2.1 with ambari-server-1.5.1.110-1.noarch), because 
> /etc/hadoop/conf{,.empty}/mapred-site.xml contains characters '&' and '>' 
> (not encoded as xml entities) for mapreduce.admin.user.env property.

> Same part in properly configured mapred-site.xml (HDP 2.1 with 2.1 stack-HDFS
