Description

Currently the documentation on http://hadoop.apache.org/common/docs/r0.23.0/hadoop-yarn/hadoop-yarn-site/ClusterSetup.html#Running_Hadoop_in_Secure_Mode is inconsistent on the recommended or default value of {{

{mapreduce.jobhistory.principal}

}}. In the section with the header: "MapReduce JobHistory Server" the principal "jhs/..." is used, but later, in the section with the header: "Configurations for MapReduce JobHistory Server:", the principal "mapred/..." is used.

Fix is to replace "mapred/..." with "jhs/...".
