2. Set the io.compression.codecs property value to: com.hadoop.compression.lzo.LzoCodec.
3. Add a description of the config modification, then click Save.
4. Expand the Custom core-site.xml section.
5. Click Add Property.
6. Add to Custom core-site.xml the following property key and value:

7. Click Save.
8. Add a description of the config modification, then click Save.
9. Restart the HDFS, MapReduce2 and YARN services.
