> I tried using bin/hbase hfile in a memory-constrained environment. It crashed
> while trying to instantiate a blockcache. Went to override the configuration
> and found I couldn't.
> Refactor HFile to remove main(), put implementation entirely in
> HFilePrettyPrinter. Said class now extends Configured and implements Tool so
> configs can be overridden on cli. Also disabled blockcache by default.
