Tamas Mate has uploaded a new patch set (#4). ( 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 two new tables to the Catalog WebUI's '/catalog' page. These tables are exposing the number of running catalog operations, which helps to better understand the catalog load and reason when the catalog is overloaded. A new 'monitor' package is created to collect the monitoring sub-classes. The new counters are called just after JNI methods are invoked, so it can notice the exceptions. The existing thrift structure is extended with the new counters, these values are unwrapped and displayed on the WebUI. Before/after pictures of the '/catalog' page can be found in the Jira.
