[jira] [Commented] (HBASE-10690) Drop Hadoop-1 support

["stack (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-10690?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13924558#comment-13924558 ] 

stack commented on HBASE-10690:
-------------------------------

Suggest that if we are removing hadoop1 that we go whole way.  Remove profiles and hbase-hadoop1 module.  Should remove dev-support/generate-hadoopX-poms.sh too and undo our current strange build process where we generate a hbase-h1.tgz and a hbase-h2.tgz bundle and just instead do hbase.tgz.

> It seems that the consensus is that supporting Hadoop-1 in HBase-1.x will be costly, so we should drop the support. 
> In this issue: 
>  - We'll document that Hadoop-1 support is deprecated in HBase-0.98. And users should switch to hadoop-2.2+ anyway. 
>  - Document that upcoming HBase-0.99 and HBase-1.0 releases will not have Hadoop-1 support. 
>  - Document that there is no rolling upgrade support for going between Hadoop-1 and Hadoop-2 (using HBase-0.96 or 0.98).
>  - Release artifacts won't contain HBase build with Hadoop-1. 
>  - We may keep the profile, jenkins job etc if we want.
