Call to Master.Hadoop/172.20.145.22 : 9000 failed Mr
description of your instances and HDFS nowhere

in the code to try to write dead jobtracker address

configured before. Just also found, window under the "Map / Reduce Locations" to "Advanced parameters" and not the same parameters under linux, window more of the following parameters.

conf.set ("mapred.job.tracker", "172.20.145.22:9001");
conf.set ("fs.default.name", "hdfs :/ / 172.20.145.22:9000");
loaded with the above two together, or the same error. I'm a little perplexed, as well as what might be the problem then?

issue has been resolved. Delete the original data and re-establish MR engineering, reconfiguring "Map / Reduce Locations", successfully executed.
