> Oozie launcher job (for MR/Pig/Hive/Sqoop action) reads the location of the
> jobtoken file from the *HADOOP_TOKEN_FILE_LOCATION* ENV var and seeds it as
> the *mapreduce.job.credentials.binary* property in the jobconf that will be
> used to launch the real (MR/Pig/Hive/Sqoop) job.
> The MR/Pig/Hive/Sqoop submission code (via Hadoop job submission) uses
> correctly the injected *mapreduce.job.credentials.binary* property to load
> the credentials and submit their MR jobs.
> The problem is that the *mapreduce.job.credentials.binary* property also
> makes it to the tasks of the MR/Pig/Hive/Sqoop MR jobs.
> If for some reason the MR/Pig/Hive/Sqoop MR code does some logic that
> triggers the credential loading, because the property is set, the credential
> loading fails trying to load a jobtoken file of the launcher job which does
> not exists in the context of the MR/Pig/Hive/Sqoop jobs.
> More specifically, we are seeing this happening with certain hive queries
> that trigger a conditional code within their RowContainer which then uses the
> FileInputFormat.getSplits() and then the TokenCache tries to load credentials
> for a file that is for the wrong job.
