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

    [ https://issues.apache.org/jira/browse/HBASE-8332?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13731835#comment-13731835 ] 

Liu Shaohui commented on HBASE-8332:
------------------------------------

[~mbertozzi]
Some tips about the patch
a, I think a sync truncate method in HbaseAdmin is better than a async one.
b, TruncateTableHandler can reuse the CreateTableHandler code in recreateTable
c. Truncate shoud keep acl info too.

> Currently truncate and truncate_preserve are only shell functions, and implemented as deleteTable() + createTable().
> Using ACLs the user running truncate, must have rights to create a table and only "global granted" users can create tables.
> Add truncate() and truncatePreserve() to HBaseAdmin/HMaster with its own ACL check.
