Hello all, I was reading the Hortonworks documentation about data governance and more precisely about atlas. As I saw, Atlas claims limited support for Kafka/storm. Does anyone know, what limited support stands for? I haven 't find anything on the web yet. Thanks in advance https://docs.hortonworks.com/HDPDocuments/HDP3/HDP-3.0.1/atlas-overview/content/apache_atlas_features.html ... View more

As I see, if I try the below query, superset returns the results successfully SELECT `added`, `channel`, `cityname`, `comment`, `countryisocode`, `countryname`, `deleted`, `delta`, `isanonymous`, `isminor`, `isnew`, `isrobot`, `isunpatrolled`, `metrocode`, `namespace`, `page`, `regionisocode`, `regionname`, `user` FROM default.druid_table_cstefan_test LIMIT 100 So I guess that the issue is due to the column __time , this column is auto-created from druid when I create the "druid datasource". __time data_type is "timestamp with local time zone" Is there any workaround? ...

Hello HC, I have successfully created an external hive table from a druid datasource. CREATE EXTERNAL TABLE druid_table_cstefan_test STORED BY 'org.apache.hadoop.hive.druid.DruidStorageHandler' TBLPROPERTIES ("druid.datasource" = "wikipedia"); I am able to run queries from the hive-interactive shell. However, if I run queries ( or preview table ) from superset SQL lab it returns fail 22 ( see attached photo ). Does anyone know anything about this error? And if yes, how can I fix this? Unfortunately, I can't find something relative in the web. Thanks in advance, every help is appreciated hive-interactive = superset database name (backend: hive) druid_table_cstefan_test = table name ... View more

However, I was wondering, if I can do something to associate "File View" with the correct cluster ID I also tried to remove the following directory on ambari server and then restart ambari # rm -rf /var/lib/ambari-server/resources/views/work/FILES\{1.0.0\}/ # ambari-server restart but it was ineffective. ...
