Description

DataStreamer.java

          if (one.getSeqno() != seqno) {
            throw new IOException("ResponseProcessor: Expecting seqno" +
                " for block " + block +
                one.getSeqno() + " but received " + seqno);
          }

There is no space between the block and the one.getSeqno(). Please change to:

          if (one.getSeqno() != seqno) {
            throw new IOException("ResponseProcessor: Expecting seqno " + one.getSeqno()
                + " for block " + block + " but received " + seqno);
          }
