Mike LaSpina commented on TEIID-2842:
-------------------------------------
Ramesh,
The files used and a doc with some instructions can be found here:
https://jaspersoft.egnyte.com/publicController.do?folderName=20140213&fileName=ecBIQgml2h
A couple of notes:
1)The doc refers to tsv files as I had to uncompress to make them work - use the .gz versions in the download link
2) Due to poor internet connection, I only included one of the omniture log files, but the example still holds
3) Once uploaded, you can try a 'Describe' in the HUE Implala web interface and get the 'compressed files not supported' error

> Teiid makes a query call "Describe table" in HiveMetadataProcessor.addTable(....). However, if the table contains compress file, HIVE2 driver would return the following execption:
> {code}
> java.sql.SQLException: AnalysisException: Failed to load metadata for table: default.omniturelogs
> CAUSED BY: TableLoadingException: Failed to load metadata for table:
> omniturelogs
> CAUSED BY: RuntimeException: Compressed text files are not supported: hdfs://localhost.localdomain:8020/user/cloudera/omniturelogs/Omniture.0.tsv.gz

> Maybe Teiid should call "DESCRIBE FORMATTED table" for table that contains compress file.
