Subject [jira] [Commented] (HBASE-7171) Initial web UI for region/memstore/storefiles details
Date Tue, 08 Dec 2015 04:50:11 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7171?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15046341#comment-15046341

Mikhail Antonov commented on HBASE-7171:
----------------------------------------

After looking into it I'm inclined to propose to make it as separate efforts. 

HFilePrettyPrinter  prints out metrics when certain cli options are used. Metrics in json
seems to be not something supported well in the version of yammer we're using (see HBASE-14534).
So I started migrating things to new yammer (now called dropwizard 3.1.2), and turned out
it's not a matter of changing couple pom files, as in some pieces they changed API quite a
bit.

So I thought to make this as following:
 - get this one in with current 'console-style pretty-printing'
 - complete migration to new yammer/dropwizard
 - complete refactoring of HFilePrettyPrinter to be like WALPrettyPrinter (support both cli
and json, as well as programmatic invocation)
