> Project: HBase
> Issue Type: Bug
> Components: Coprocessors
> Reporter: Duo Zhang
> Assignee: Duo Zhang
> Priority: Major
> Fix For: 3.0.0, 2.2.0

> Attachments: HBASE-21550.patch

>
> Before 2.0, we will pass a HTableDescriptor and the CPs can modify the schema
> of a table, but now we will pass a TableDescriptor, which is immutable. I
> think it is correct to pass an immutable instance here, but we should have a
> return value for this method to allow CPs to return a new TableDescriptor.
