Subject [jira] [Commented] (HBASE-6929) Publish Hbase 0.94 artifacts build against hadoop-2.0
Date Thu, 18 Oct 2012 00:16:04 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6929?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13478518#comment-13478518

Enis Soztutar commented on HBASE-6929:
--------------------------------------

bq. Another possible solution would be to provide artifact hbase-test that would have classifier
either hadoop1 or hadoop2 based on for which version it was compiled
We should not do this for h1, since that would break maven compatibility that our previous
artifacts (0.94.0, 0.94.1, etc) was released with artifact name hbase, and classifier tests.
However, maybe we can do it for hadoop2, not sure how easy it would be to create hbase-tests
artifact with classifier hadoop-2. Since maven-deploy hardcodes "tests" classifier, this might
not be possible at all.
bq. Long time ago I filed HBASE-4850 but haven't had much time to devote to it since then.
What versions of hadoop? If between hadoop1 and hadoop2, then I don't think we can resolve
this easily without creating a shim layer for pretty much everything.

> Downstream projects (flume, hive, pig, etc) depends on hbase, but since the hbase binaries
build with hadoop-2.0 are not pushed to maven, they cannot depend on them. AFAIK, hadoop 1
and 2 are not binary compatible, so we should also push hbase jars build with hadoop2.0 profile
into maven, possibly with version string like 0.94.2-hadoop2.0.
