How to back up HBase data

[sa...@hotmail.com]

Hi, everyone. Recently I encountered a problem about data loss of HBase. So it comes to the question that how to back up HBase data to recover table records if HBase or HDFS crash. What about copy the directory of HBase to another directory in HDFS? Could someone mind giving me some advice? Thanks a lot!

Best Wishes!

You can either do exports at the HBase API level (a la Export class), or you
can force flush all your tables and do an HDFS level copy of the /hbase
directory (using distcp for example).

You can use Export class.
Please take a look at hbase-2225 as well.
