Hadoop-openpgp-codec is a project mainly written in Java, it's free.
Codec for Hadoop adding OpenPGP encryption using Bouncy Castle
Tommie Gannert [email protected] 2011-08-18
This project implements a org.apache.hadoop.io.compress.CompressionCodec
for use in with Hadoop.
Created to upload encrypted files from the Flume logging framework into Amazon S3.
Currently, this is just a bunch of code written for testing purposes, not to be used in production. The decompression part has not been tested at all. The compressor outputs valid GPG files.
Build the package using Maven:
mvn packageAdd target/*.jar target/lib/*.jar to the CLASSPATH of Hadoop, using
hadoop-env.sh, or in the Flume case; flume-env.sh.
If you are using Oracle's JVM and you are not in the USA, you have to switch JCE policy files to enable strong encryption.
In the Hadoop configuration file, add a property io.compression.codecs with
org.apache.hadoop.io.compress.DefaultCodec,org.apache.hadoop.io.compress.GzipCodec,com.spotify.hadoop.openpgp.OpenPgpCodecThis casues files ending in .gpg to be automatically filtered through the
codec.
To make Flume use it by default for the collector sinks, add `flume.collector.dfs.compress.codec'':
com.spotify.hadoop.openpgp.OpenPgpCodecThe various options used by the codec are global, and specified in the class documentation.
Will be written if we decide to actually use it...
