Thanks Brian.
Just to clarify do you use something like below? 1. hdfs dfs -copyFromLocal /var/tmp/t.bcp hdfs://rhes564.hedat.net:9000/misc/t.bcp 2. CREATE EXTERNAL TABLE <TABLE> name (col1 INT, col2 string, .)

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.
