[jira] [Commented] (HDFS-9382) Track the acks for the packets which are sent from ErasureCodingWorker as part of reconstruction work
[ https://issues.apache.org/jira/browse/HDFS-9382?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=15007553#comment-15007553 ] Zhe Zhang commented on HDFS-9382: - Great idea Uma. With this proposed work, we should probably revisit whether we should unify block reader and writer for client and DN. I believe [~libo-intel] has explored the idea to some extent. > Track the acks for the packets which are sent from ErasureCodingWorker as > part of reconstruction work > - > > Key: HDFS-9382 > URL: https://issues.apache.org/jira/browse/HDFS-9382 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: datanode >Affects Versions: 3.0.0 >Reporter: Uma Maheswara Rao G >Assignee: Uma Maheswara Rao G > > Currently we are not tracking the acks for the packets which are sent from DN > ECWorker as part of reconstruction work.

Maybe we can consider the optimization after most of the functionalities of EC are satisfied. > Track the acks for the packets which are sent from ErasureCodingWorker as > part of reconstruction work > - > > Key: HDFS-9382 > URL: https://issues.apache.org/jira/browse/HDFS-9382 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: datanode >Affects Versions: 3.0.0 >Reporter: Uma Maheswara Rao G >Assignee: Uma Maheswara Rao G > > Currently we are not tracking the acks for the packets which are sent from DN > ECWorker as part of reconstruction work.
