https://community.cloudera.com/t5/Support-Questions/How-Atlas-is-notified-when-there-is-a-change-in-any-data/m-p/209625#M171579 <P><A rel="user" href="https://community.cloudera.com/users/17468/sababaig.html" nodeid="17468">@Saba Baig</A>, Hive have the notion of post execution hooks which handles hive events and messages. Any Hive event triggers a hook message (<A href="https://hive.apache.org/javadocs/r1.2.2/api/org/apache/hadoop/hive/ql/hooks/PostExecute.html">post execution hook</A>) and Atlas receives and processes the hook message. When table B is created from table A - a hook message is triggered and sent out about this event and atlas updates the related entities - hive_table, hive_db. This will also be used to track lineage and other hive event information in atlas. </P> Fri, 16 Jun 2017 05:49:39 GMT ssubramanian 2017-06-16T05:49:39Z
