             Summary: Erasure coding: client should update and commit block based on acknowledged size
                 Key: HDFS-9342
                 URL: https://issues.apache.org/jira/browse/HDFS-9342
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: erasure-coding
    Affects Versions: 3.0.0
            Reporter: Zhe Zhang
            Priority: Critical


For non-EC files, we have:
{code}
protected ExtendedBlock block; // its length is number of bytes acked
{code}

For EC files, the size of {{DFSStripedOutputStream#currentBlockGroup}} is incremented in {{writeChunk}} without waiting for ack. And both {{updatePipeline}} and {{commitBlock}} are based on size of {{currentBlockGroup}}.
