Subject Distributed Cache - for iterators?
Date Thu, 28 Mar 2013 15:45:41 GMT
Hey everyone,

In Hadoop Map Reduce, the Configuration class can pass String parameters (via the Context
argument to map and reduce). Likewise, the Map<String, String> options argument in Iterator
init allows the same functionality for Accumulo iterators.

However, for more complex parameters, Hadoop has a DistributedCache which is available to
all of the mappers and reducers. Is there any similar functionality for Accumulo iterators,
or does all of the information need to be sent as a String through options?

Also, are there any problems with sending exceptionally long Strings in the options argument?
