We are pushing the compressed text files into HDFS directory for Hive EXTERNAL table, then using an INSERT on the table using ORC storage. We are letting Hive handle the ORC file creation process.

Data volume is ~1TB/day, we are really trying to avoid unpacking them to condition the data. A few days of research has us ready to implement custom input/output formats to handle the ingest. Any other suggestions that may be less effort with low impact to load times? Thanks, Bryan G.
