Subject [jira] [Commented] (HDFS-7749) Erasure Coding: Add striped block support in INodeFile
Date Tue, 23 Jun 2015 18:34:02 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7749?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14598137#comment-14598137
] 

Zhe Zhang commented on HDFS-7749:
---------------------------------

[~jingzhao] A quick question while rebasing this patch:

In {{CacheReplicationMonitor}}, should we call BM instead of FSN to get the stored block?
{code}
-      BlockInfoContiguous blockInfo = blockManager.
-            getStoredBlock(new Block(cblock.getBlockId()));
+      BlockInfo blockInfo = namesystem.getStoredBlock(new Block(cblock.getBlockId()));
{code}
