Uma Maheswara Rao G updated HDFS-8137: -------------------------------------- Attachment: HDFS-8137-1.patch > Sends the EC schema to DataNode as well in EC encoding/recovering command > ------------------------------------------------------------------------- > > Key: HDFS-8137 > URL: https://issues.apache.org/jira/browse/HDFS-8137 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Kai Zheng > Assignee: Uma Maheswara Rao G > Attachments: HDFS-8137-0.patch, HDFS-8137-1.patch > > > Discussed with [~umamaheswararao] and [~vinayrpet], we should also send the > EC schema to DataNode as well contained in the EC encoding/recovering > command. The target DataNode will use it to guide the executing of the task. > Another way would be, DataNode would just request schema actively thru a > separate RPC call, and as an optimization consideration, DataNode may cache > schemas to avoid repeatedly asking for the same schema twice. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
