[jira] [Updated] (HADOOP-11804) Shaded Hadoop client artifacts and minicluster
[ https://issues.apache.org/jira/browse/HADOOP-11804?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Gautham Banasandra updated HADOOP-11804:
----------------------------------------
Release Note:
The `hadoop-client` Maven artifact available in 2.x releases pulls
Hadoop's transitive dependencies onto a Hadoop application's classpath.
This can be problematic if the versions of these transitive dependencies
conflict with the versions used by the application.
HADOOP-11804 adds new `hadoop-client-api` and
`hadoop-client-runtime` artifacts that shade Hadoop's dependencies
into a single jar. This avoids leaking Hadoop's dependencies onto the
application's classpath.
