---------------------------------
> CLONE - NN should consider current EC tasks handling count from DN while
> assigning new tasks
> --------------------------------------------------------------------------------------------
>
> Key: HDFS-10092
> URL: https://issues.apache.org/jira/browse/HDFS-10092
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: datanode, namenode
> Reporter: dragon
> Assignee: Uma Maheswara Rao G
> Fix For: HDFS-7285
>
>
> Currently NN will pick the (maxStreams-XmitsCount) number of ECtasks at a
> time for assigning to the respective DN.
> {code}
> //get datanode commands
> final int maxTransfer = blockManager.getMaxReplicationStreams()
> - xmitsInProgress;
> {code}
> But right now we increment xmitsInProgress count at DN only for regular
> replication tasks but not for ECWorker tasks.
> So, either we should treat this logic separately for EC or we should consider
> EC current task handling count form DN.
> This jira for discussing more for this case.
