> RU precheck requires "mapreduce.jobhistory.recovery.store.class" property to be set in the mapred-site.xml with value "org.apache.hadoop.mapreduce.v2.hs.HistoryServerLeveldbStateStoreService"
> With this value set, the HDP 2.2 level MapRed history server can not start. It shows an err about class  org.apache.hadoop.mapreduce.v2.hs.HistoryServerLeveldbStateStoreService does not exist.
> When downgrading, the mapred properties added to pass the RU precheck needs to be removed.
