title: HBase Row Key Split Algorithm
body: <p>I am trying to store some data for every phone number on Hbase.
  The row key I will be using is reverse(PhoneNumber) for better distribution as most of the number for a particular country will start with same country code leading to hot-spotting.
  I will me moving this data from mysql to Hbase.</p>
  
  <p>I took a random sample of 1 million phone numbers and took 200 splits of UniformSplit and HexStringSplit  -the two predefined String algorithms in Hbase.</p>
  
  <p>With UniformSplit only 8 regions get the data.
  With HexStringSplit 81 regions get the data .</p>
  
  <p>Is there any other Split Algorithm I can use or any other Strategy.</p>
