[jira] [Commented] (HBASE-8124) TableMapReduceUtils should distribute dependency jars using an hbase config

    [ https://issues.apache.org/jira/browse/HBASE-8124?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13603806#comment-13603806 ]

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

tmpjars is actually a Hadoop configuration, we cannot rename it.

> When users invoke TableMapReduceUtils#addDependencyJars, directly or indirectly, the discovered jars are added to the jobconf via the configuration point "tmpjars". That means that, if I want to use one jobconf as the basis of another, and I blanket copy all "hbase.*" confs, the dependency jar list will be missed. Since the dependency jars are critical for successful execution of the job, and not an internal API passed between different MR components, this config point should be renamed to something starting with "hbase."
