Andrew Purtell commented on HBASE-18060: ---------------------------------------- [~vincentpoon] The TestInterfaceAudienceAnnotations failure is probably related to this change. Fix that and this is good from my perspective. > Backport to branch-1 HBASE-9774 HBase native metrics and metric collection > for coprocessors > ------------------------------------------------------------------------------------------- > > Key: HBASE-18060 > URL: https://issues.apache.org/jira/browse/HBASE-18060 > Project: HBase > Issue Type: New Feature > Affects Versions: 1.4.0, 1.3.2, 1.5.0 > Reporter: Vincent Poon > Assignee: Vincent Poon > Attachments: HBASE-18060.branch-1.3.v1.patch, > HBASE-18060.branch-1.3.v2.patch, HBASE-18060.branch-1.3.v3.patch, > HBASE-18060.branch-1.3.v4.patch, HBASE-18060.branch-1.v1.patch, > HBASE-18060.branch-1.v2.patch, HBASE-18060.branch-1.v3.patch, > HBASE-18060.branch-1.v4.patch > > > I'd like to explore backporting HBASE-9774 to branch-1, as the ability for > coprocessors to report custom metrics through HBase is useful for us, and if > we have coprocessors use the native API, a re-write won't be necessary after > an upgrade to 2.0. > The main issues I see so far are: > - the usage of Java 8 language features. Seems we can work around this as > most of it is syntactic sugar. Will need to find a backport for LongAdder > - dropwizard 3.1.2 in Master. branch-1 is still on yammer metrics 2.2. Not > sure if these can coexist just for this feature -- This message was sent by Atlassian JIRA (v6.3.15#6346)
