Subject [jira] [Commented] (ACCUMULO-3923) VFS ClassLoader doesnt' work with KeywordExecutable
Date Mon, 13 Jun 2016 15:41:21 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-3923?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15327631#comment-15327631

Dave Marion commented on ACCUMULO-3923:
---------------------------------------

bq. Oh, is this property not also used by the Java ClassLoader? Maybe that was part of my
confusion.

The property is used by both the bootstrap_hdfs.sh script and the VFS classloader. My changes
to bootstrap_hdfs.sh are in the parsing of the property from accumulo-site.xml.

> Trying to make the VFS classloading stuff work and it doesn't seem like ServiceLoader
is finding any of the KeywordExecutable implementations.
> Best I can tell after looking into this, VFSClassLoader (created by AccumuloVFSClassLoader)
has all of the jars listed as resources, but when ServiceLoader tries to find the META-INF/services
definitions, it returns nothing, and thus we think the keyword must be a class name. Seems
like a commons-vfs bug.
