My map tasks need some configuration data, which I would like to distribute via the Distributed Cache.
The Hadoop MapReduce Tutorial shows the usage of the DistributedCache class, roughly as follows:
// In the driver
JobConf conf = new JobConf(getConf(), WordCount.class);
DistributedCache.addCacheFile(new Path(filename).toUri(), conf);
// In the mapper
Path myCacheFiles = DistributedCache.getLocalCacheFiles(job);
However, DistributedCache is marked as deprecated in Hadoop 2.2.0.
What is the new preferred way to achieve this? Is there an up-to-date example or tutorial covering this API?
