Hey there, I am using hadoop 0.20.2. I 've successfully installed LZOCompression following these steps: https://github.com/kevinweil/hadoop-lzo
I have some MR jobs written with the new API and I want to compress intermediate data. Not sure if my mapred-site.xml should have the properties: <property> <name>mapred.compress.map.output</name> <value>true</value> </property> <property> <name>mapred.map.output.compression.codec</name> <value>com.hadoop.compression.lzo.LzoCodec</value> </property> or: <property> <name>mapreduce.map.output.compress</name> <value>true</value> </property> <property> <name>mapreduce.map.output.compress.codec</name> <value>com.hadoop.compression.lzo.LzoCodec</value> </property> How can I check that the compression is been applied?
