Hi there- Take a look at this for starters: http://hbase.apache.org/book.html#schema
1) double-check your row-keys (sanity check), that's in the Schema Design chapter. http://hbase.apache.org/book.html#performance 2) if not using bulk-load - re-create regions, do this regardless of using MR or non-MR. 3) if not using MR job and are using multiple threads with the Java API, take a look at HTableUtil. It's on trunk, but that utility can help you.
