In the checkHistoryParsing() function, after
{code}
HistoryFileInfo fileInfo = jobHistory.getJobFileInfo(jobId);
{code}
a thread named MoveIntermediateToDone will be launched to move history file
from done_intermediate to done directory.
If the history file is moved,
{code}
HistoryViewer viewer = new HistoryViewer(fc.makeQualified(
fileInfo.getHistoryFile()).toString(), conf, true);
{code}
will throw IOException，because the history file is not found.
