Tsz Wo Nicholas Sze commented on HDFS-8138: ------------------------------------------- CODEC is not a good name. How about changing it to ERASURE_CODE? > Refine or extend EC command to support all cases > ------------------------------------------------ > > Key: HDFS-8138 > URL: https://issues.apache.org/jira/browse/HDFS-8138 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Kai Zheng > Assignee: Vinayakumar B > > Currently a {{CODEC}} command is used to distribute stripping recovery > command to DataNode. Discussed with [~umamaheswararao] and [~vinayrpet] > further, we may need to refine or extend the command to support all cases, as > we may distribute encoding and recovering tasks in both stripping and > non-stripping cases. We may have two ways: 1) a single command but uses a > flag in it to denote all the cases; 2) more commands. > This will also consider how to layout, optimize or document relevant info > contained in the the corresponding command related to the block group, so > DataNode will be able to restore such info according to the concrete command. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
