[jira] [Commented] (HBASE-15583) Discuss mutable vs immutable HTableDescriptor

["Konstantin Ryakhovskiy (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-15583?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15351023#comment-15351023 ] 

Konstantin Ryakhovskiy commented on HBASE-15583:
------------------------------------------------

They are used in the hbase-client, HTable.getTableDescriptor().
From my perspective, since it is a public API, then it makes sense to:
- first mark it as deprecated
- and create new method to return mutable (modifiable) HTableDescriptor.

>     PS Should UnmodifyableHTableDescriptor be renamed to UnmodifiableHTableDescriptor?
> It should be named ImmutableHTableDescriptor to be consistent with collections naming. Let's do this as a subtask of the parent jira, not here. Thinking about it though, why would we return an Immutable HTD in HTable.getTableDescriptor() versus a mutable HTD in Admin.getTableDescriptor(). It does not make sense. Should we just get rid of the Immutable ones?
> We also have UnmodifyableHRegionInfo which is not used at the moment it seems.
