Subject [jira] [Updated] (HBASE-11845) HFile tool should implement Tool, disable blockcache by default
Date Wed, 27 Aug 2014 23:32:58 GMT

     [ https://issues.apache.org/jira/browse/HBASE-11845?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Nick Dimiduk updated HBASE-11845:

    Release Note: 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

> 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.
