Subject [jira] [Comment Edited] (HBASE-14376) move hbase spark integration examples into their own module
Date Fri, 15 Jan 2016 23:03:39 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14376?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15102640#comment-15102640

------------------------------------------------------------------

I'm having some difficulties with Phoenix Spark integration due to dependencies and general
Scala compiler crap* that I assume will bedevil HBase users once we have a Spark integration
module as well. I strongly prefer holding spark/scala dependencies to one module, which furthermore
may be optionally skipped during build, for the time being. 

* - Sometimes, if you have an optional dependency (as part of the transitive dependency set),
Maven+Scala won't pull it in, the Scala compiler will synthesize a stub, this isn't sufficient
for something, and the compiler will NPE. At least 2.10.3 and 2.10.4 versions of the compiler
have this problem. Might come up at any time as the set of transitive dependencies change.
