Subject [jira] [Commented] (HDFS-5257) addBlock() retry should return LocatedBlock with locations else client will get AIOBE
Date Fri, 25 Oct 2013 07:04:31 GMT

    [ https://issues.apache.org/jira/browse/HDFS-5257?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13805104#comment-13805104

Jing Zhao commented on HDFS-5257:

bq. So I feel better both should be present.

Yeah, we should fix the both ends. The server side fix guarantee the correct retry, while
the client side's fix allows ppl to have a temporary fix in case they do not want to upgrade
server immediately. 

+1 for the new patch.
