Using a LocalResource instance to distribute files and resources for a MapReduce job

ungarala — Wed, 16 Mar 2016 11:14:47 GMT

There is an objective in HDPCD:Java exam to use LocaResource in MapReduce Jobs. I haven't come across any example on web to understand this. Appreciate if someone can give me pointers in understanding how LocalResource can be used in MR jobs? How is this different from cache files?

@Sanjay Ungarala - thank you for pointing this out. We decided a while back to remove this objective from the HDPCD:Java exam, but the website was not changed accordingly. I just updated the website and removed that objective. LocalResource is used heavily in YARN, but it is beyond the scope of our Java exam.
