Sampling HBase table keyspace <p>I'd like to build random samples of a HBase table's rowkey space.</p> <p>Say, I'd like to have roughly 1% of the keys from HBase that are randomly distributed across the table. What's the best way of doing this?</p> <p>I suppose I could write a MapReduce job that processed all the data and pulled 1/100 of the keys... or perhaps use a coprocessor.</p>
