Hi, I have a Clouderas CDH3u3 installed on my cluster and mapred.child.env set to "LD_LIBRARY_PATH=/usr/lib/hadoop-0.20/lib/native/Linux-amd64-64" (with libsnappy.so in the folder) in mapred-site.xml. Cloudera says that Snappy is included in their hadoop-0.20-native package and it is also installed on each of the nodes.
But when I run a mapreduce task with "mapred.map.output.compression.codec" set to "org.apache.hadoop.io.compress.SnappyCodec" I get an exception: java.lang.RuntimeException: native snappy library not available Any idea why? Thanks, Marek M.
