-----------------------------------

             Summary: HBase translator - boolean and biginteger values are not translated correctly
                 Key: TEIID-3623
                 URL: https://issues.jboss.org/browse/TEIID-3623
             Project: Teiid
          Issue Type: Bug
    Affects Versions: 8.7.1.6_2
         Environment: Hbase: 1.1.1
Phoenix: 4.5.0-HBase-1.1
            Reporter: Juraj Duráni
            Assignee: Steven Hawkins


*1. Boolean values:* The Teiid translates the value true/false as 1/0, but HBase does not support integer representation of boolean values [1].

*2. BigInteger values ( <= -2):* Teiid's bigInteger data type is wider than HBase's bigint (as wide as long) type, so it make sense to define column in HBase as e.g. _decimal(30,0)_ and map it to Teiid's biginteger type.
>From Teiid's point of view: There is no problem if inserted value is greater than or equal to -1. But if the value is less than -1, then a ClassCastException is thrown [2]. Phoenix driver require something like "UPSERT INTO smalla (intkey, bigintegervalue) VALUES (1, -10*.0*)"

[1]
*Query:* insert into hbase.smalla (intkey, booleanvalue) values (55, true)
*Column definition:*
- source: booleanvalue boolean
- VDB: BooleanValue boolean OPTIONS (nameinsource 'booleanvalue', NATIVE_TYPE 'boolean')
*Stack trace:*
insert_boolean.log

[2]
*Query:* insert into hbase.smalla (intkey, bigintegervalue) values (55, -10)
*Column definition:*
- source: bigintegervalue decimal(20,0)
- VDB: BigIntegerValue biginteger OPTIONS (nameinsource 'bigintegervalue', NATIVE_TYPE 'decimal')
*Stack trace:*
insert_biginteger.log
