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

             Summary: ErasureCodingWorker#processErasureCodingTasks should not fail to process
remaining tasks due to one invalid ECTask
                 Key: HDFS-9113
                 URL: https://issues.apache.org/jira/browse/HDFS-9113
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: datanode
    Affects Versions: HDFS-7285
            Reporter: Uma Maheswara Rao G
            Assignee: Uma Maheswara Rao G
            Priority: Minor


Currently processErasureCodingTasks method submits ecTasks to thread pool service for processing
the tasks. While submitting we initialize ReconstructAndTransferBlock with each ecTask and
submit it. There are chances ReconstructAndTransferBlock initialization can fail due to wrong
values as we had preconditions for parameter validations in Ctor. Anyway, whatever may be
the case, processErasureCodingTasks should not fail and throw exceptions out as it could prevent
processing other tasks in the list.
