This is because Hadoop 20 does not support distributed cache in local mode. My understanding is that it would be part of Hadoop 22.

When running in mapreduce mode, the distributed cache is always enable (e.g. replicated join). However, I never find such method, DistributedCache.getLocalCacheFiles(job), which get the cached file from the local disk. So, how does pig read these files from local disk? I am looking at the pig 0.7 source code. Thanks, -Gang
