Enis Soztutar commented on HBASE-11845:
---------------------------------------
+1. Nick, let's get this in.
Agreed with Andrew, maybe we should keep HFile main so that if any script is
directly using HFile it will still work. However, HFile.main() should just call
HFPP.main directly instead of what it does now so that Tool mechanics work.
> 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.
