> Proposal to create an external table in Trafodion metadata and map it to an 
> existing HBase table.
> Listed below are proposed syntax and semantics rules for this support.
> Proposed Syntax:
>   create external table T (…column definitions…) map to hbase table T;
>  this will create a Trafodion table in metadata with columns specified 
> in ‘column definitions’ and 
> map that definition to an externally created native HBase table T.
>   alter table T add column b;
>   alter table T drop column b;
>  will add and drop column ‘b’ from Trafodion metadata. Underlying mapped 
> HBase table will not be affected.
>   drop table T;
>  will drop external table T from Trafodion metadata. Underlying mapped 
> HBase table will not be affected.
>  Semantics:
>  If table T is specified in a DDL or DML statement without an explicit 
> schema (like: drop table T, or select * from T
>,or create table Tlike  like T), 
> then it will be first searched as a regular table in default regular schema. 
> If not found, then it will be searched as a mapped table.
> So a regular table T will take precedence over a mapped table T.
>It is recommended that one does not create a regular table and a mapped 
> table with the same name to avoid confusion.
>  Restrictions:
> To limit the initial scope of this work, there will be some restrictions. 
> Some of these may be lifted
> at a later time.
>  insert, update and delete statements on mapped tables will not be 
> initially supported.
>  a mapped table cannot be aligned format table
>  A primary key clause must be specified
>  external and hbase mapped table names must be the same
>  All non-primarykey and non-nullable columns must have a default value. 
> This is needed to handle missing values   
>in the underlying HBase table.
>  creation of a Trafodion index on a mapped table will not be supported
> This proposal will be updated with additional syntax and semantics rules 
> going forward.

If resetMyZNodeFailedTime_ is true, then this if statement will always 
evaluate to true.   Just verifying that is the desired outcome.

Trafodion can support ANSI SQL with-clause, so the documentation need to sync
