@TonyQiu  Sorry been away for a while.  Creating a table in a kerberized cluster should be possible as hbase. I just tried it out see the flow below.. I didn't need to specifically kinit as the user hbase had a valid Kerberos ticket Switch to hbase user [root@malindi keytabs]# su - hbase Last login: Wed May 25 21:51:56 CEST 2022 Check if kerberos ticket is valid [hbase@malindi ~]$ klist Ticket cache: FILE:/tmp/krb5cc_1016 Default principal: hbase-jair@KENYA.KE Valid starting Expires Service principal 05/25/2022 21:51:57 05/26/2022 21:51:57 krbtgt/KENYA.KE@KENYA.KE Connect to hbase shell as hbase [hbase@malindi ~]$ hbase-shell List existing tables hbase(main):006:0> list TABLE ATLAS_ENTITY_AUDIT_EVENTS atlas_titan 2 row(s) in 0.6660 seconds => ["ATLAS_ENTITY_AUDIT_EVENTS", "atlas_titan"] Create table emp hbase(main):007:0> create 'emp', 'personal data', 'professional data' 0 row(s) in 4.9500 seconds => Hbase::Table - emp List tables validate emp was created hbase(main):009:0> list TABLE ATLAS_ENTITY_AUDIT_EVENTS atlas_titan emp 3 row(s) in 0.0130 seconds => ["ATLAS_ENTITY_AUDIT_EVENTS", "atlas_titan", "emp"] Describe table emp hbase(main):010:0> describe 'emp' Table emp is ENABLED emp COLUMN FAMILIES DESCRIPTION {NAME => 'personal data', BLOOMFILTER => 'ROW', VERSIONS => '1', IN_MEMORY => 'false', KEEP_DELETED_CELLS => 'FALSE', DATA_BLOCK_ENCODING => 'NONE', TTL => 'FOREVER', COMPRESSION => 'NONE', MIN_VERSIONS => '0', BLOCKCACHE => 'true', BLOCKSIZE => '65536', REPLICATION_SCOPE => '0'} {NAME => 'professional data', BLOOMFILTER => 'ROW', VERSIONS => '1', IN_MEMORY => 'false', KEEP_DELETED_CELLS => 'FALSE', DATA_BLOCK_ENCODING => 'NONE', TTL => 'FOREVER', COMPRESSION => 'NONE', MIN_VERS IONS => '0', BLOCKCACHE => 'true', BLOCKSIZE => '65536', REPLICATION_SCOPE => '0'} 2 row(s) in 0.8770 seconds Update table hbase(main):011:0> alter 'emp', {NAME => 'metrics', BLOCKSIZE => '16384', COMPRESSION => 'SNAPPY'} Updating all regions with the new schema... 0/1 regions updated. 1/1 regions updated.
