title: When should one prefer Mahout's SequentialAccessSparseVector over RandomAccessSparseVector?
body: <p>I'm a newbie with regards to mahout. I would like to build my own algorithms with mahout's tools. I'm quite puzzled with the of usage Mahout's <code>SequentialAccessSparseVector</code> and <code>RandomAccessSparseVector</code>. Could someone suggest when should one prefer over the other?</p>
  
  <p>Thanks</p>
