Subject [jira] [Commented] (HDFS-7822) Make webhdfs handling of URI stardard compliant
Date Mon, 17 Aug 2015 18:54:46 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7822?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14700030#comment-14700030

Allen Wittenauer commented on HDFS-7822:
----------------------------------------

I keep meaning to update this JIRA...

We can do both. REST allows for incompatible changes by increasing the version number in the
URL.  Fixed clients should try v2.  If it fails, the fixed client knows that the server hasn't
been upgraded so falls back to the broken v1 protocol.  Broken clients won't know the difference
because they'll only try v1.

> As seen in HDFS-7816, webhdfs client is not encoding URI properly. But since webhdfs
is often used as the compatibility layer, we cannot simply fix it and break the compatibility.
Instead, we should stage the fix so that breakages caused by incompatibility can be minimized.
