尝试使用压缩运行mapreduce作业

hadoop jar \
  /usr/lib/hadoop-mapreduce/hadoop-mapreduce-examples.jar \
  randomtextwriter \
  -Ddfs.replication=1 -Dmapreduce.output.fileoutputformat.compress=true -Dmapreduce.output.fileoutputformat.compress.codec=com.hadoop.compression.lzo.LzoCodec \
  /tmp/randomtextwriter

使用将lzo分发到群集中所有节点的地块。即便如此，我还是犯了下面的错误

Getting below error 
Error: java.lang.IllegalArgumentException: Compression codec com.hadoop.compression.lzo.LzoCodec was not found.
