Here, in this HBase<\/strong> article, we will learn all the Table Management commands in HBase. These HBase Commands are Create table, List table, Disable table, Enable table, Describe\u00a0& Alter table, Exist table and Drop table. <\/span><\/p>\n

Also, we will see how to use these several Shell Commands<\/strong> in HBase using Java API. Moreover, we will discuss syntax & example of Table Commands in HBase<\/span><\/p>\n

So, let’s explore Commands in HBase.<\/p>\n

    <\/td>\n<\/td>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
    in HBase shell, we can create this table:<\/span><\/p>\n
