@Poorvi Sachar What does the atlas application log say, when this request is made? which version of HDP is this? Is it possible to attach the application log here for debugging? ... View more

@Bilal Arshad From the logs, it looks like port on which Atlas is trying to run is already blocked.[Address already in use] Exception in thread "main" MultiException[java.lang.ExceptionInInitializerError, java.net.BindException: Address already in use] So, I would recommend you to follow the below steps. First stop atlas by running, atlas_stop.py script and make sure atlas is stopped. Now, with the help of netstat command, check if some other process is already using the atlas port(21000) and kill that process id [kill -9 <pid>]. Now, restart atlas using atlas_start.py and check if that helps. If the above steps are not helping, then I would recommend you to change the atlas default port from 21000 to some other port(eg: 31000) and then restart. Let me know how it goes. ... View more

@DIVYASREE TAMILMANI (In the context of HDP-2.5 release) As part of storm data model, kafka topic and hbase table are modeled as datasets. What it means is, whenever a storm topology is submitted, StormHook captures and posts all the metadata of spouts, bolts and endpoints including data sets(like kafka_topic and hbase_table) to Atlas. Please note there is no hook/plugin specifically for kafka which would ingest metadata of kafka topics into atlas. For more detailed information, please take a look at the below documentation. http://atlas.incubator.apache.org/StormAtlasHook.html http://atlas.incubator.apache.org/Bridge-Falcon.html ... View more
