This project provides support for reading LZO compressed tables from Impala.
Generally you should also install the Hadoop-lzo project which provides support for indexing the files produced by the lzop program.
Tables containing lzo compressed files must be created in Hive with: stored as INPUTFORMAT 'com.hadoop.mapred.DeprecatedLzoTextInputFormat' OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'
To build the library do: You must set the environment variable IMPALA_HOME to the root of an Impala development tree. cmake . make at the top level will put the resulting libimpalalzo.so in the build directory. This file should be moved to ${IMPALA_HOME}/lib/. OR any directory that is in the LD_LIBRARY_PATH of your running impalad servers.
