In this step, we are going to write data into HBase table "guru99" First, we have to write code for insert and retrieve values from HBase by using- HBaseLoading.java program. It is a byte in and a byte out, which means everything that has to be written in HBase needs to be converted/encoded to a byte array, and while reading, it can again be converted/decoded to an equivalent representation. Mapping data types to fields in HBase HBase is a data model that is similar to Google’s big table designed to provide quick random access to huge amounts of structured data. We could specify that in the column descriptor and enable data type-specific compression such as variable-length integer encoding. Some databases are a mix between different types, but in general, they fit under the following main categories. NoSQL databases are often categorised under four main types. Hackolade was specially adapted to support the data types and attributes behavior of HBase. Sqoop. Attributes data types.
