Subject [jira] [Commented] (YARN-2185) Use pipes when localizing archives
Date Thu, 18 Jan 2018 20:15:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-2185?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16331129#comment-16331129

Miklos Szegedi commented on YARN-2185:
--------------------------------------

I intentionally added the javac warning, so that we deprecate the additional saving of the
jar file that adds disk overhead. The unit test issue is ZK and unrelated. The ASF license
warning is a test file left around by some other unit tests I think.

> Currently the nodemanager downloads an archive to a local file, unpacks it, and then
removes it.  It would be more efficient to stream the data as it's being unpacked to avoid
both the extra disk space requirements and the additional disk activity from storing the archive.
