For the failed test
[org.apache.phoenix.end2end.index.ChildViewsUseParentViewIndexIT.testParentViewIndexWithSpecializedChildViews](https://ci-hadoop.apache.org/job/Phoenix/job/Phoenix-PreCommit-GitHub-PR/job/PR-1704/17/testReport/org.apache.phoenix.end2end.index/ChildViewsUseParentViewIndexIT/testParentViewIndexWithSpecializedChildViews/),
seems it's an existing bug on view indexes because @jpisaac also got this
issue on views extending pk. But now it also happened on views without
extending pk. Maybe we can create a Jira for this bug and mark this test as
@ignore for now.

> We'll run into issues if updatable sibling views overlap with each other. For
> example, say you have the following hierarchy:
> T (A, B, C)
> V1 (D, E) FROM T WHERE A = 1
> V2 (F, G) FROM T WHERE A = 1 and B = 2
> In this case, there's no way to update both V1 and v2 columns. Secondary
> indexes wouldn't work either, if you had one on each V1 & V2.
> We should restrict updatable views to
> - views that filter on PK column(s)
> - sibling views filter on same set of PK column(s)
