Subject [jira] [Commented] (HBASE-18109) Assign system tables first (priority)
Date Sat, 03 Jun 2017 22:07:05 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18109?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16036105#comment-16036105

stack commented on HBASE-18109:
-------------------------------

Excellent. Patch looks good. It does make a simple distinction between system and user-space
tables. This won't address the [~yangzhe1991] issue IIUC? Did you consider playing w/ the
executor so it pops high-priority issues ahead of others queued (and then add facility to
mark a priority on a Procedure?)?

> Need this for stuff like the RSGroup table, etc. Assign these ahead of user-space regions.
