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

             Summary: CLONE - Erasure Coding: fix the copy constructor of BlockInfoStriped
and BlockInfoContiguous
                 Key: HDFS-10127
                 URL: https://issues.apache.org/jira/browse/HDFS-10127
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: dragon
            Assignee: Vinayakumar B


{code}
BlockInfoStriped(BlockInfoStriped b) {
  this(b, b.getSchema());
  this.setBlockCollection(b.getBlockCollection());
}
{code}

{code}
protected BlockInfoContiguous(BlockInfoContiguous from) {
  this(from, from.getBlockCollection().getPreferredBlockReplication());
  this.triplets = new Object[from.triplets.length];
  this.setBlockCollection(from.getBlockCollection());
}
{code}

We should define a copy constructor in the {{BlockInfo}}, and call it from these two {{subclass}}.
   I also notice a NullPointerException test failure of {{TestBlockInfo.testCopyConstructor}}
in latest branch which is related to this.
