Management of Tables
1) See what tables are available

HBase (main) > list

2) Create a table

# syntax: Create <table> {NAME = <family>, VERSIONS = <versions>} # For example: Creating a table T1, with two family name:f1,f2, and Version number is 2 hbase (main) > create ' t1 ', {NAME = ' F1 ', VERSIONS = 2},{name = ' F2 ', VERSIONS = 2}
