> A typo in HistoryViewer makes some code useless.
> The typo is
> Limits.reset(conf);
> We should use jobConf instead of conf.
> With the typo, the following code becomes useless:
> {code}
> final Path jobConfPath = new Path(jobFile.getParent(), jobDetails[0]
> + "_" + jobDetails[1] + "_" + jobDetails[2] + "_conf.xml");
> final Configuration jobConf = new Configuration(conf);
> jobConf.addResource(fs.open(jobConfPath), jobConfPath.toString());
> {code}
> The code wants to load the configuration from the Job configuration file and reset the Limits based on the new configuration loaded from the Job configuration file.
> So this typo is apparent.
