-------------------------------------
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()}}.
