Now I'm trying to use viewfs for NameNode Federation with HDP3.1.I found "ViewFs is not supported on Hive clusters." on the following page.https://docs.hortonworks.com/HDPDocuments/Ambari-18.104.22.168/managing-and-monitoring-ambari/content/amb_...
Does it mean viewfs is not supported on Hive services?(I can't get the meaning of "Hive clusters".)Thank you for your any help 🙂
One update. Hive seems to have an issue about handling "viewfs://"?
For example, hive db creation got failed with permission error even if the permission of the target hdfs dir is 777.
hdfs dfs -ls -d viewfs://fed/user/hadoop/warehouse/hadoop_viewfs6.db
drwxrwxrwx - hadoop hadoop 0 2019-04-24 07:44 viewfs://fed/user/hadoop/warehouse/hadoop_viewfs6.db
Hive DB creation got failed with the hdfs dir.
0: jdbc:hive2://XXXX > create database hadoop_viewfs6 location '/user/hadoop/warehouse/hadoop_viewfs6.db';
Error: Error while compiling statement: FAILED: HiveAccessControlException Permission denied: user [hadoop] does not have [WRITE] privilege on [viewfs://fed/user/hadoop/warehouse/hadoop_viewfs6.db] (state=42000,code=40000
