> Exporting a table with a common schema, like hashes as the key, will result in a sorted exported file. When imported with org.apache.hadoop.hbase.mapreduce.Import, region servers can be overloaded one by one by requests by the MapReduce job, since the rows are imported in sequential order, and a regions span ranges in sequential order. This is more likely to happen with lots of data and not a lot of regions.
