• Answer:

  There are a lot of ways to get data out of an HBase table like running the export map/reduce job. You can read about this and other here http://blog.sematext.com/2011/03/11/hbase-backup-options/ If you want to control which rows/cells are written you can do that with http://pig.apache.org/ x = LOAD 'hbase://<sourceDatabaseName>' USING org.apache.pig.backend.hadoop.hbase.HBaseStorage( '<family:qualifier>', '<family:qualifier2>','-loadKey true') AS (ID: bytearray , Value1:chararray , Value2:chararray); STORE x INTO '<destFileName>' USING CSVExcelStorage(['<delimiter>' [,{'YES_MULTILINE' | 'NO_MULTILINE'} [,{'UNIX' | 'WINDOWS' | 'UNCHANGED'}]]]);
