i have some hypothesis, but it's only my speculation : i think that, when i call scanner.iterator().hasNext() it has to check all rows in the table to find (or not) next rowId (because hasnext time rise in line correlation with a table size). Maby problem is in sorting rowId in the table? i will try to change rowId format. i try checkout latest version of hbase and try to check the same case today. Acure.
