Subject [jira] [Commented] (HDFS-8065) Erasure coding: Support truncate at striped group boundary
Date Mon, 18 Jul 2016 01:09:20 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8065?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15381607#comment-15381607

Kai Zheng commented on HDFS-8065:

Thanks [~rakeshr] for working on this. My concern is, without the clear design being sorted
out first for arbitrary truncation (HDFS-7622), opening the codes to allow truncate at striped
group boundary may be not a good idea, since the feature would be hard to document and use.
It would be hardly tell a good use case, and why users would do truncate on block group size
boundary? If other size is used to truncate, exception will be thrown. Users will be confused.

I do think we need to document in the release note saying that truncate isn't supported yet
for striping files.
