Subject [jira] [Commented] (HADOOP-10105) remove httpclient dependency
Date Tue, 26 May 2015 12:04:19 GMT

Tsuyoshi Ozawa commented on HADOOP-10105:
-----------------------------------------

[~ajisakaa], you're right. But I don't think we should revert the change in this case - Hadoop
Compatibility guideline doesn't mention any policies about dependency upgrades. Application
developers who use AmIpFilter can avoid the issue just by adding old httpclient with the version
a dependency. How about writing it on a release note of YARN-3217?

> httpclient is now end-of-life and is no longer being developed.  Now that we have a dependency
on {{httpcore}}, we should phase out our use of the old discontinued {{httpclient}} library
in Hadoop.  This will allow us to reduce {{CLASSPATH}} bloat and get updated code.
