I need to take a dump of one table in HBase and need it in a text file/csv format? I looked for scan
, export
and get
commands in HBase
If we need to have more control with Java code, hope below link will be helpful.

This will backup a single HBase table as CSV format in local filesystem. We need to pre-define the list of columns we needed from a single column family. This code uses necessary jars to connect HBase table along with OpenCSV jar to write CSV records.
Assumption here is all the columns are only string.
