             Summary: Erasure Coding: Balance the tasks num on nodes when reconstruct ec recovery 
                 Key: HDFS-15876
                 URL: https://issues.apache.org/jira/browse/HDFS-15876
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: ec, erasure-coding
    Affects Versions: 3.0.0
            Reporter: chan


ErasureCodingWork:addTaskToDatanode

 

at the end,this will assign the task to target[0] node,but the node may remain many tasks

 

should we consider the num of task on nodes and balance them not just assign the tasks to target[0] node
