Nick Dimiduk updated HBASE-11845:
---------------------------------
Release Note: HFileTool now accepts configuration overrides in the usual
way. Blockcache is disabled by default. (was: HFile inspection is no longer
available through the HFile class. Now this
functionality resides entirely in HFilePrettyPrinter. `bin/hbase
hfile` does
the right thing. This
utility now accepts -Dconfig overrides.)
> HFile tool should implement Tool, disable blockcache by default

> 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.
