Subject [jira] [Commented] (HBASE-16448) Custom metrics for custom replication endpoints
Date Fri, 19 Aug 2016 21:18:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16448?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15428849#comment-15428849
] 

Andrew Purtell commented on HBASE-16448:
----------------------------------------

bq. Adding the interface annotation requires adding dependencies on hadoop-annotation and
hbase-common libraries to hbase-hadoop-compat

Ugh, ok nevermind :-)

lgtm
Will commit later today

> ReplicationEndpoints contain a MetricsSource class that can update a fixed set of key
replication metrics. It does not, however, allow a developer implementing a custom ReplicationEndpoint
to create/update custom metrics unique to the new endpoint's use case. 
> As it turns out, MetricsSource wraps a class, which in turn wraps a class, that implements
the Hadoop BaseSource interface, which does allow for custom metrics. Simply having the two
wrappers implement BaseSource as well with pass-through methods should be straightforward,
and would allow replication endpoints to use these generic metric methods.
