prashantwason opened a new pull request #2152:
URL: https://github.com/apache/hudi/pull/2152


   Using the added API, publish metrics after each level of the DAG completed 
in hudi-test-suite.
   
   
   ## What is the purpose of the pull request
   
   HUDI metrics are published at two stages:
   1. When an action completed (e.g. HoodieMetrics.updateCommitMetrics)
   2. When the JVM is shutdown (Metrics.java addShutdownHook)
   
   hudi-test-suite includes multiple jobs each of which is an action on the 
table. All these jobs are run in a single JVM. Hence, currently some metrics 
are not published till the entire hudi-test-suite run is over.
   
   Enhancements:
   1. Allow metrics to be published after each job
   2. Flush metrics so redundant metrics (from the last job) are not published 
again.
   
   ## Brief change log
   
   Added Metrics.flush()
