Using compression

One of the most important features of HBase is the use of data compression. It's important because:

  • Compression reduces the number of bytes written to/read from HDFS

  • Saves disk usage

  • Improves the efficiency of network bandwidth when getting data from a remote server

HBase supports the GZip and LZO codec. Our suggestion is to use the LZO compression algorithm because of its fast data decompression and low CPU usage. As a better compression ratio is preferred for the system, you should consider GZip.

Unfortunately, HBase cannot ship with LZO because of a license issue. HBase is Apache-licensed, whereas LZO is GPL-licensed. Therefore, we need to install LZO ourselves. We will use the hadoop-lzo library, which brings splittable LZO compression to Hadoop.

In this recipe, we will describe how to install LZO and how to configure HBase to use LZO compression.

Getting ready

Make sure Java is installed on the machine on which hadoop-lzo is to be built.

Apache Ant is required to build...

Ever wonder why speech recognition systems don't understand the Scottish accent, or what would happen if an astronaut only ate mac 'n' cheese, or other spurious reflections you'd have at a bar?
