FAQ
Best to ask Impala questions on the Impala user lists
(impala-user@cloudera.org), which I've added here.

Yes Impala can query LZO tables iff they are also indexed. Have you
installed the gplextras packages required for this functionality, as
documented at http://www.cloudera.com/content/cloudera-content/cloudera-docs/Impala/latest/Installing-and-Using-Impala/ciiu_lzo.html

Can you use impala on an external table that has LZO compressed files?

Your query has the following error(s):

AnalysisException: Failed to load metadata for table: searches CAUSED BY:
TableLoadingException: Failed to load metadata for table: searches CAUSED
BY: RuntimeException: Compressed file not supported without compression
input format:
hdfs://hadoop-master.mycompany.com:8020/user/root/rails/archive/search/2013/05/06/part-r-00000.lzo
