Zhihong Ted Yu commented on HBASE-4050: --------------------------------------- Good idea. ServiceLoader is used widely in hadoop. e.g. from Token.java: {code} for (TokenIdentifier id : ServiceLoader.load(TokenIdentifier.class)) { tokenKindMap.put(id.getKind(), id.getClass()); } {code} I would vote for hbase-hadoop-compat module. > Update HBase metrics framework to metrics2 framework > ---------------------------------------------------- > > Key: HBASE-4050 > URL: https://issues.apache.org/jira/browse/HBASE-4050 > Project: HBase > Issue Type: New Feature > Components: metrics > Affects Versions: 0.90.4 > Environment: Java 6 > Reporter: Eric Yang > Assignee: Alex Baranau > Priority: Critical > Fix For: 0.96.0 > > Attachments: 4050-metrics-v2.patch, 4050-metrics-v3.patch, > HBASE-4050.patch > > > Metrics Framework has been marked deprecated in Hadoop 0.20.203+ and 0.22+, > and it might get removed in future Hadoop release. Hence, HBase needs to > revise the dependency of MetricsContext to use Metrics2 framework. -- This message is automatically generated by JIRA.
