Subject [jira] [Commented] (HDFS-9535) Newly completed blocks in IBR should not be considered under-replicated too quickly
Date Sat, 12 Dec 2015 01:11:46 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9535?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15053897#comment-15053897
] 

Masatake Iwasaki commented on HDFS-9535:
----------------------------------------

bq. The guarantee Jing Zhao proposed in addStoredBlock makes sense to me.

I too agree with the fix. Should we have checking {{if (!bc.isStriped())}} around {{addExpectedReplicasToPending}}?
