Updating the Snappy Codec to Enable Avro Data Compression

Updating the Snappy Codec to Enable Avro Data Compression

To enable Avro data compression with the Snappy codec, replace the default Snappy .jar file with the updated version.
  1. On the machine where you installed the Informatica server, replace the
    snappy-java-1.0.4.1.jar
    file in the server installation with the
    snappy-java-1.1.0.1.jar
    file. Replace the .jar at the following path:
    <Server_Installation>\services\shared\hadoop\<Hadoop_Distribution>\lib
  2. On the machines where you installed and run Hadoop, replace the
    snappy-java-1.0.4.1.jar
    file with the
    snappy-java-1.1.0.1.jar
    file. Replace the .jar at the following path:
    <Hadoop_rpm>\services\shared\hadoop\<Hadoop_Distribution>\lib
