@USMAN_HAIDER  There is this step below did you perform that? Kerberos must be specified as the security mechanism for Hadoop infrastructure, starting with the HDFS service. Enable Cloudera Manager Server security for the cluster on an HDFS service. After you do so, the Cloudera Manager Server automatically enables Hadoop security on the MapReduce and YARN services associated with that HDFS service. In the Cloudera Manager Admin Console: Select Clusters > HDFS-n. 1.Click the Configuration tab. 2.Select HDFS-n for the Scope filter. 3.Select Security for the Category filter. 4.Scroll (or search) to find the Hadoop Secure Authentication property. 5.Click the Kerberos button to select Kerberos: Please revert             ...

Hi As per the link, https://zeppelin.apache.org/docs/0.8.0/usage/rest_api/interpreter.html#restart-an-interpreter   To restart zeppelin interpreter we need to know interpreter id , which we are unable to find .   https://zeppelin.apache.org/docs/0.8.0/usage/rest_api/interpreter.html#restart-an-interpreter   Also interpreter restart can only be done with admin user, hence that also needs to be passed via script.     Thanks ASIF. ...

Asif, please see if the below table creation query helps. This is used while restoring HBase table: create 'atlas_titan' , {NAME => 'e', BLOOMFILTER => 'ROW', VERSIONS => '1', IN_MEMORY => 'false', KEEP_DELETED_CELLS => 'FALSE', DATA_BLOCK_ENCODING => 'FAST_DIFF', TTL => '2592000', COMPRESSION => 'GZ', MIN_VERSIONS => '0', BLOCKCACHE => 'true', BLOCKSIZE => '65536', REPLICATION_SCOPE => '0'} ,{NAME => 'g', BLOOMFILTER => 'ROW', VERSIONS => '1', IN_MEMORY => 'false', KEEP_DELETED_CELLS => 'FALSE', DATA_BLOCK_ENCODING => 'FAST_DIFF', TTL => '2592000', COMPRESSION => 'GZ', MIN_VERSIONS => '0', BLOCKCACHE => 'true', BLOCKSIZE => '65536', REPLICATION_SCOPE => '0'} , {NAME => 'i', BLOOMFILTER => 'ROW', VERSIONS => '1', IN_MEMORY => 'false', KEEP_DELETED_CELLS => 'FALSE', DATA_BLOCK_ENCODING => 'FAST_DIFF', TTL => '2592000', COMPRESSION => 'GZ', MIN_VERSIONS => '0', BLOCKCACHE => 'true', BLOCKSIZE => '65536', REPLICATION_SCOPE => '0'} , {NAME => 'l', BLOOMFILTER => 'ROW', VERSIONS => '1', IN_MEMORY => 'false', KEEP_DELETED_CELLS => 'FALSE', DATA_BLOCK_ENCODING => 'FAST_DIFF', TTL => '2592000', COMPRESSION => 'GZ', MIN_VERSIONS => '0', BLOCKCACHE => 'true', BLOCKSIZE => '65536', REPLICATION_SCOPE => '0'} , {NAME => 'm', BLOOMFILTER => 'ROW', VERSIONS => '1', IN_MEMORY => 'false', KEEP_DELETED_CELLS => 'FALSE', DATA_BLOCK_ENCODING => 'FAST_DIFF', TTL => '2592000', COMPRESSION => 'GZ', MIN_VERSIONS => '0', BLOCKCACHE => 'true', BLOCKSIZE => '65536', REPLICATION_SCOPE => '0'} , {NAME => 's', BLOOMFILTER => 'ROW', VERSIONS => '1', IN_MEMORY => 'false', KEEP_DELETED_CELLS => 'FALSE', DATA_BLOCK_ENCODING => 'FAST_DIFF', TTL => '2592000', COMPRESSION => 'GZ', MIN_VERSIONS => '0', BLOCKCACHE => 'true', BLOCKSIZE => '65536', REPLICATION_SCOPE => '0'} ...

Hello @ASIF123    Atlas Janus is an HBase Table, created with Column Family specification only. The DDL of the concerned Atlas Table is available in the HMaster UI & Master Logs, when Atlas Service is initialised for 1st time. However, Column Families are added eventually & each Row of the concerned Table has Different Column Qualifier. In short, there is no Static Definition of Atlas Janus Table.    Any Phoenix Table or View mapping requires explicit specification of the Column Family & Column Qualifier. Henceforth, the Phoenix Table or View DDL will be specific to Customer's Env. Your team can review the Atlas Janus Table Output via Scan & confirm the Column Qualifier against each Column Family. Accordingly, the Phoenix Table or View can be created.    - Smarak ... View more
