Importing data from MySQL via single client
The most usual case of data migration might be importing data from an existing RDBMS into HBase. For this kind of task, the most simple and straightforward way could be to fetch the data from a single client and then put it into HBase, using the HBase Put API. It works well if there is not too much data to transfer.
This recipe describes importing data from MySQL into HBase using its Put API. All the operations will be executed on a single client. MapReduce is not included in this recipe.
