Date Wed, 27 Aug 2014 23:14:58 GMT
Nick Dimiduk created HBASE-11845:
------------------------------------

             Summary: HFile tool should extend Configured, disable blockcache by default
                 Key: HBASE-11845
                 URL: https://issues.apache.org/jira/browse/HBASE-11845
             Project: HBase
          Issue Type: Improvement
          Components: HFile
            Reporter: Nick Dimiduk
            Assignee: Nick Dimiduk
            Priority: Minor
             Fix For: 0.99.0, 2.0.0, 0.98.7


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.
