--------------------------------

             Summary: Optimize method BlockInfoStriped#findSlot to reduce time complexity.
                 Key: HDFS-17053
                 URL: https://issues.apache.org/jira/browse/HDFS-17053
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: farmmamba


Currently, in method findSlot. there exists codes snippet below:
{code:java}
for (; i < getCapacity(); i++) {
  if (getStorageInfo(i) == null) {
    return i;
  }
} {code}
it will compute （triplets.length / 3;) every iteration, I think this can be optimized.
