Sheng Liu commented on HADOOP-9989:
-----------------------------------
+1 I have the same issue, mrv1 in CDH also needs
"mapreduce.job.credentials.json" be a json file
> Bug introduced in HADOOP-9374, which parses the -tokenCacheFile as binary
> file but set it to the configuration as JSON file.

> The code in JIRA HADOOP-9374's patch introduced a bug, where the value of the

> mapreduce.job.credentials.json parameter in GenericOptionsParser, which
> cannot be parsed by JobSubmitter when it gets the value.
