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

             Summary: Reuse NameStringPair#Builder instances in loops
                 Key: HBASE-11308
                 URL: https://issues.apache.org/jira/browse/HBASE-11308
             Project: HBase
          Issue Type: Task
            Reporter: Ted Yu
            Priority: Minor


The following code is from HColumnDescriptor#convert() but the pattern can be found in other classes, such as HBaseAdmin:
{code}
    for (Map.Entry<String, String> e : this.configuration.entrySet()) {
      NameStringPair.Builder aBuilder = NameStringPair.newBuilder();
      aBuilder.setName(e.getKey());
      aBuilder.setValue(e.getValue());
      builder.addConfiguration(aBuilder.build());
    }
{code}
NameStringPair.Builder instance can be reused across iterations of the loop.
This would save creation of short-lived objects.
