James Taylor commented on PHOENIX-2783:
---------------------------------------
[~maryannxue] did a good job of explaining the precedence that Phoenix uses
over on CALCITE-1208. The primary key column would take precedence in the
example you listed. Note that any non primary key column can be prefixed with
it's column family (which is 0 by default if not explicitly named), so this
should work as well:
{code}
select i, "0".i from tbl;
{code}
> Creating secondary index with duplicated columns makes the catalog corrupted

> Key: PHOENIX-2783
> URL: https://issues.apache.org/jira/browse/PHOENIX-2783
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.7.0
> Reporter: Sergey Soldatov
> Assignee: Sergey Soldatov
> Attachments: PHOENIX-2783-1.patch, PHOENIX-2783-2.patch,
> PHOENIX-2783-3.patch, PHOENIX-2783-4.patch, PHOENIX-2783-INIT.patch

> Simple example
> {noformat}
> create table x (t1 varchar primary key, t2 varchar, t3 varchar);
> create index idx on x (t2) include (t1,t3,t3);
> {noformat}
> cause an exception that duplicated column was detected, but the client
> updates the catalog before throwing it and makes it unusable. All following
> attempt to use table x cause an exception ArrayIndexOutOfBounds. This problem
> was discussed on the user list recently.
> The cause of the problem is that check for duplicated columns happen in
> PTableImpl after MetaDataClient complete the server createTable.
> The simple way to fix is to add a similar check in MetaDataClient before
> createTable is called.
> Possible someone can suggest a more elegant way to fix it?
