> Related to a fixed issue MAPREDUCE-6230 which cause a Job to get into error state. In
that situation Job's second or some later attempt could succeed but those later attempts'
history file will all be lost. Because the first attempt in error state will copy its history
file to intermediate dir while mistakenly think of itself as lastattempt. Jobhistory server
will later move the history file of that error attempt from intermediate dir to done dir while
ignore the rest of that job attempt's later history files in intermediate dir.
