Subject [jira] [Updated] (HDFS-8033) Erasure coding: stateful (non-positional) read from files in striped layout
Date Fri, 24 Apr 2015 21:35:39 GMT

     [ https://issues.apache.org/jira/browse/HDFS-8033?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Zhe Zhang updated HDFS-8033:
----------------------------
    Attachment: HDFS-8033.005.patch
                HDFS-8033.004.patch

Good observations Walter! We've assumed the cell size should be a multiple of packet size;
it's a great idea to gracefully handle potential misalignments. 

The 005 patch adds the logic Walter suggested. To avoid changing the behavior of super class,
it overrides the ByteBuffer reader. 

[~jingzhao] Could you take a look and see if it also addresses your earlier comments? Thanks!
