Subject [jira] [Commented] (HDFS-7822) Make webhdfs handling of URI stardard compliant
Date Mon, 23 Feb 2015 15:44:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7822?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14333412#comment-14333412

Kihwal Lee commented on HDFS-7822:

Here is the initial proposal for starting the discussion
- Make the server-side to work with both the old (non-compliant) and the new (compliant) clients.
- Make the client-side to work either in the standard mode or in the compatibility mode based
on a config variable.
- The default config can be flipped to the standard mode after some number of releases.
- Optionally, at some point in the future (after 2 major version changes?), remove the compatibility

> 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.
