Query LZO-compressed Tables Using Impala Failed With Error: "Query aborted, unable to fetch data" (Doc ID 1611352.1)

Last updated on JANUARY 20, 2014

Applies to:

Big Data Appliance Integrated Software - Version 2.1.1 and later
Linux x86-64

Symptoms

The Oracle Big Data Appliance (BDA) cluster has Hadoop version Hadoop 2.0.0-cdh4.2.0 and Impala version is v0.6. Followed the instructions on http://www.cloudera.com/content/cloudera-content/cloudera-docs/Impala/1.0.1/Installing-and-Using-Impala/ciiu_lzo.html to configure access of LZO-compressed data with Impala. The installation set up went well and the indexer also worked.

However, querying the LZO-compressed table from impala failed with the following error:

Impala-shell:

[cloudera1:21000] > select * from lzopro;
Query: select * from lzopro
Query aborted, unable to fetch data

 However it works fine from hive CLI.
