Subject [jira] [Commented] (HBASE-19018) Use of hadoop internals that require bouncycastle should declare bouncycastle dependency
Date Mon, 16 Oct 2017 19:35:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-19018?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16206451#comment-16206451
] 

Sean Busbey commented on HBASE-19018:
-------------------------------------

Some additional context for bystanders: test dependencies aren't included transitively. we
rely on the hadoop-minicluster dependency for the mini dfs/yarn/etc clusters. that dependency
is just a pom that pulls in various bits from across the hadoop project so that it will have
those mini cluster implementations. This involves pulling in a fair number of test-jars. Without
a bunch of archeological work on Hadoop's repo and jira it's hard to say if the lack of bouncycastle
in the set of dependencies is intentional or not. But with only a failed use of an internal
class to go on, we'll be hard pressed to change it.

> The tests for HBASE-15806 rely on a Hadoop internal class, {{KeyStoreTestUtil}}, which
in turn relies on the Bouncycastle library for certificate generation.
> when building / running with Hadoop 2.7.1, we accidentally get a bouncycastle implementation
via a transitive dependency of {{hadoop-minikdc}}. When attempting to run against Hadoop 3.0.0-alpha4
and 3.0.0-beta1 (and presumably future Hadoop 3.y releases), this bouncycastle jar is no longer
pulled in and we fail with a CNFE.
