-------------------------------------
Hi - I am working with Ivan on this issue. I can confirm that the DESCRIBE FORMATTED also
does not work on compressed files using Impala. Queries seems to work fine, but we can
not get the schema using describe.
Impala/ HIVE2: Unsupported compress file
-----------------------------------------
Key: TEIID-2842
URL:
https://issues.jboss.org/browse/TEIID-2842
Project: Teiid
Issue Type: Bug
Components: Query Engine
Affects Versions: 8.6
Environment: Impala/HIVE2 with Teiid
Reporter: Ivan Chan
Assignee: Ramesh Reddy
Labels: teiid
Teiid makes a query call "Describe table" in
HiveMetadataProcessor.addTable(....). However, if the table contains compress file,
HIVE2 driver would return the following execption:
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.
