Subject [jira] [Commented] (HDFS-12872) EC Checksum broken when BlockAccessToken is enabled
Date Fri, 01 Dec 2017 19:56:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12872?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16274861#comment-16274861

Xiao Chen commented on HDFS-12872:

Regarding the related question, Eddy pointed out that my test was writing all 0 bytes - stupid
me. But even writing random bytes I still see exactly the same physical blocks on disks....
Will look into that in a bit, please comment if you have any thoughts. Thanks!
