-------------------------------------------------------------
Proposed solution:
There's 2 ways to tackle this. Either we extract an Impala conforming tablename
from given Kudu tablename or give it a standard placeholder name for users to
replace with what they need.
Extracting a name can be achieved by string manipulation (for example by
considering only the last after-decimal portion of Kudu tablename, or ignoring
the decimal in the tablename), however it will result in a name that wouldn't
match the original name and may be non-intuitive for most users.
Using a standard placeholder name would clearly communicate the need to update
this name to user-desired name, while maintaining consistency with Impala
naming conventions.

> Under the Tables section of Kudu Web UI, for a selected table, the table
> metrics display a CREATE TABLE statement that can be run to make Impala
> cognizant of that table. However, in generation of this statement, the table
> name tries to match the original Kudu tablename which may not always be
> acceptable as a tablename for Impala. For example, Kudu accepts dot in
> tablename, Impala does not.
> A statement like the following throws an invalid tablename error in Impala –
