[jira] [Created] (HBASE-15641) Shell "alter" should do a single modifyTable operation

Gary Helmling created HBASE-15641:
-------------------------------------

             Summary: Shell "alter" should do a single modifyTable operation
                 Key: HBASE-15641
                 URL: https://issues.apache.org/jira/browse/HBASE-15641
             Project: HBase
          Issue Type: Improvement
          Components: shell
            Reporter: Gary Helmling


When performing an "alter" on multiple column families in a table, then shell will perform a separate {{Admin.modifyColumn()}} call for each column family being modified, with all of the table regions being bulk-reopened each time.  It would be much better to simply apply all the changes to the table descriptor, then do a single call to {{Admin.modifyTable()}}.
