Subject [jira] [Commented] (HDFS-8328) Follow-on to update decode for DataNode striped blocks reconstruction
Date Thu, 04 Jun 2015 03:42:38 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8328?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14572058#comment-14572058

Zhe Zhang commented on HDFS-8328:
---------------------------------

Thanks Yi for the update (and for this great work on DN!). The latest patch looks good to
me; +1 on committing it

Just as a future reference for consolidation with client side striped reading code:
# We can consider moving {{StripeReader}} from HDFS-8319 to the util class and subclass it
for DN
# {{readMinimumStripedData4Recovery}} is the counterpart of {{StripeReader#readStripe}}

> Current the decode for DataNode striped blocks reconstruction is a workaround, we need
to update it after the decode fix in HADOOP-11847.
