[jira] [Commented] (YARN-1442) change yarn minicluster base directory via system property

    [ https://issues.apache.org/jira/browse/YARN-1442?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14109849#comment-14109849 ] 

Ken Krugler commented on YARN-1442:
-----------------------------------

I'm curious why we wouldn't use the existing yarn.nodemanager.xxx conf settings for controlling where to put files. That's what I had originally done, and would seem like the most consistent approach.

Related, I was assuming dfs.data.dir would control where to put HDFS blocks, but instead there's an undocumented MiniDFSCluster.HDFS_MINIDFS_BASEDIR property...why?

> The yarn minicluster used for testing uses the "target" directory by default. We use gradle for building our projects and we would like to see it using a different directory. This patch makes it possible to use a different directory by setting the yarn.minicluster.directory system property.
