@Takefumi Oide, Password should be minimum 8 characters with minimum one alphabet and one numeric. Unsupported special characters are " ' \ ` Below is the regex check for password in HDP 3.0 if not bool(re.search(r'^(?=.*[0-9])(?=.*[a-zA-Z]).{8,}$', atlas_admin_password)) or bool(re.search('[\\\`"\']', atlas_admin_password)) . -Aditya

@yadir Aguilar This is a permission issue. You need to give permissions on the folder to admin user or create directory as hdfs user su hdfs hdfs dfs -mkdir /user/d (or) su hdfs hdfs dfs -chown admin:admin /user/d . If you are using a kerberized environment, you should do a kinit with hdfs keytab and then run the above commands kinit -kt /etc/security/keytabs/hdfs.headless.keytab {user-principal} . Please "Accept" the answer if this helps.

@chaouki trabelsi, Are you running ambari agent as a non-root user or root user. If you are running as a non-root user, you need to follow these steps. https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.5/bk_security/content/_how_to_configure_an_ambari_agent_for_non-root.html . -Aditya

@Shesh Kumar, You can use Ranger Authorizer to achieve this. You need to create policy with deny conditions in order to make this work. https://cwiki.apache.org/confluence/display/RANGER/Deny-conditions+and+excludes+in+Ranger+policies . Please "Accept" the answer if this helps. . -Aditya

@dalin qin, In HDP 3.0, all managed tables should be transactional. Please enable ACID and make the table as transactional and try again. You can read more about ACID here https://docs.hortonworks.com/HDPDocuments/HDP3/HDP-3.0.0/managing-hive/content/hive_acid_operations.html . Please "Accept" the answer if this helps. . -Aditya

@Paramesh malla, You need to run the kinit command before running the job. For example, to do kinit with spark keyta, follow below steps 1) Get the principal klist -kt /etc/security/keytabs/spark.headless.keytab 2) Do kinit kinit -kt /etc/security/keytabs/spark.headless.keytab <principal-from-1st-command> . Run the job after running the kinit command and it should not give "Invalid credentials, no valid tgt found.". Hope this helps 🙂 Please "Accept" the answer if this helps. . -Aditya

@Adi Jabkowsky, New hive entities will be synced automatically if you enable "Hive Atlas Hook" in hive configs. Whenever you create a database or table, a message is posted to kafka topic using hive hooks and the same message is read by atlas and the corresponding entity is created in Atlas. For testing, you can create a sample database,table and check in Atlas UI . Please "Accept" the answer if this is helpful. . -Aditya

@Anjali Shevadkar, This might be a lame question. Are you sure that you are connecting to the right HiveServer ? Can you please copy the url from hive configs and try connecting to it Go to Ambari -> Hive -> Summary -> HiveServer2 JDBC URL (Copy this url) and try to connect to it and see if this works. . -Aditya

@Takefumi Oide, If you want to provide "All" permissions, selecting only "All" will suffice. if you want to give selected permissions, you can select the permissions you need. Yes. I agree that we can select "All" and "update" which may not be required. This is just a UI related thing but doesn't affect any permissions. Hope this helps. Please take a moment to Accept the answer if this helped 🙂
