I just committed this. Thanks, Jeff

In the future, large numbers are usually more readable as products in the source (e.g. 1024L
\* 1024 \* 1024).

> In filecache.DistributedCache.java, the constant DEFAULT_CACHE_SIZE is set to 1 MB, while
the value of local.cache.size in conf/hadoop-default.xml is 10 GB. I'm assuming these two
values should be consistent, and that 10 GB is the appropriate value.
