[jira] [Commented] (HBASE-18893) shell 'alter' command no longer distinguishes column add/modify/delete

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

    [ https://issues.apache.org/jira/browse/HBASE-18893?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16184291#comment-16184291 ] 

Mike Drob commented on HBASE-18893:
-----------------------------------

One small issue is that we can specify multiple column families in one alter command, so it might still make sense to batch them.

> After HBASE-15641 all 'alter' commands go through a single modifyTable call at the end, so we no longer can easily distinguish add, modify, and delete column events. This potentially affects coprocessors that needed the update notifications for new or removed columns.
> Let's let the shell still make separate behaviour calls like it did before without undoing the batching that seems pretty useful.
