Subject [jira] [Updated] (HADOOP-9741) Make build created indexed jars
Date Wed, 17 Jul 2013 23:34:49 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-9741?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Hitesh Shah updated HADOOP-9741:
--------------------------------

    Attachment: INDEX.LIST

Attaching an index file for hadoop-common-3.0.0-SNAPSHOT.jar. It is relative to the top of
the jar so re-location of the jar itself should not affect this.

The performance improvement from what I have seen is quite small - around 10-20 ms when cycling
through the jars in the hadoop classpath with a test program.

Given your concerns with jar-of-jars and the other tomcat issue that I had not come across,
I am becoming inclined to not push this in until I can prove more substantial gains on a cluster.
