Tamas Mate has uploaded a new patch set (#14). ( http://gerrit.cloudera.org:8080/13806 )
Change subject: IMPALA-6663: Expose current DDL metrics on WebUI ...................................................................... IMPALA-6663: Expose current DDL metrics on WebUI This change adds a new '/operations' tab to the Catalog WebUI. On this page the users can see two summary tables, the first report is based on how many catalog operations are running and which tables are involved. The second report shows the number of catalog operations on table level. A new 'monitor' package is created to collect the monitoring classes. Each DDL/FinalizeDML/ResetMetada request get a class with common base class. The output of these classes are summarized and can be accessed with a new JNI call. A screenshot of the new '/operations' page can be found in the Jira. Testing: Unit tests were added to test the counters and a web server test to verify the availability of the page.
