Restoring HBase data by importing dump files from HDFS

The HBase Import utility is used to load data that has been exported by the Export utility into an existing HBase table. It is the process to restore data from the Export utility backup solution.

We will look at the usage of the Import utility in this recipe.

Getting ready

First, start your HDFS and HBase cluster.

We will import the files that we exported in the previous recipe into our hly_temp table. If you do not have those dump files, refer to the Exporting HBase table to dump files on HDFS recipe, to generate the dump files in advance. We assume the dump files are saved in the /backup/hly_temp directory.

The Import utility uses MapReduce to import data. Add the HBase configurable file (hbase-site.xml) and dependency JAR files to Hadoop class path on your client node.

How to do it...

To import dump files into the hly_temp table:

1. 1. Connect to your HBase cluster via HBase Shell and create the target table if it does not exist:
