Suresh Srinivas updated HADOOP-9090: ------------------------------------ Assignee: Mostafa Elhemali > Support on-demand publish of metrics > ------------------------------------ > > Key: HADOOP-9090 > URL: https://issues.apache.org/jira/browse/HADOOP-9090 > Project: Hadoop Common > Issue Type: New Feature > Components: metrics > Reporter: Mostafa Elhemali > Assignee: Mostafa Elhemali > Priority: Minor > Attachments: HADOOP-9090.2.patch, > HADOOP-9090.justEnhanceDefaultImpl.2.patch, > HADOOP-9090.justEnhanceDefaultImpl.3.patch, > HADOOP-9090.justEnhanceDefaultImpl.4.patch, > HADOOP-9090.justEnhanceDefaultImpl.5.patch, > HADOOP-9090.justEnhanceDefaultImpl.6.patch, > HADOOP-9090.justEnhanceDefaultImpl.7.patch, > HADOOP-9090.justEnhanceDefaultImpl.8.patch, > HADOOP-9090.justEnhanceDefaultImpl.9.patch, > HADOOP-9090.justEnhanceDefaultImpl.patch, HADOOP-9090.patch > > > Updated description based on feedback: > We have a need to publish metrics out of some short-living processes, which > is not really well-suited to the current metrics system implementation which > periodically publishes metrics asynchronously (a behavior that works great > for long-living processes). Of course I could write my own metrics system, > but it seems like such a waste to rewrite all the awesome code currently in > the MetricsSystemImpl and supporting classes. > The way this JIRA solves this problem is adding a new method > publishMetricsNow() to the MetricsSystemImpl() class, that does a synchronous > out-of-band push of the metrics from the sources to the sink. I also add a > method to MetricsSinkAdapter (putMetricsImmediate) to support that change. -- This message is automatically generated by JIRA.
