             Summary: Accumulo translator: problem comparing number literals
                 Key: TEIID-3933
                 URL: https://issues.jboss.org/browse/TEIID-3933
             Project: Teiid
          Issue Type: Bug
          Components: Misc. Connectors
    Affects Versions: 8.12.3
            Reporter: Jan Stastny

When accessing Accumulo instance using accumulo translator with table DDL defined in the model's metadata, there are problems filtering the output in from clause.
For example, when there is a comparison between a column of type long with literal value 3, an exception, whose cause is below, is thrown on accumulo's side:
{code:sql}
SELECT * FROM accumulo.SmallA WHERE LongNum>3
{code}
{code:plain}
Caused by: java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Long

{code}
but when I provide a value higher, than can be saved in integer, thus the type of the literal is inferred as long, the query runs as expected.
{code:sql}
SELECT * FROM accumulo.SmallA WHERE LongNum>30000000000000000000
{code}

Similar problems I had with
||Column type||Literal||Inferred type||Rootcause message||
|long|3|Integer|java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Long|
|biginteger|3|Integer|java.lang.ClassCastException: java.lang.Integer cannot be cast to java.math.BigInteger|
|double|3.0|BigDecimal|java.lang.ClassCastException: java.math.BigDecimal cannot be cast to java.lang.Double|
|float|3.0|BigDecimal|java.lang.ClassCastException: java.math.BigDecimal cannot be cast to java.lang.Float|
rest of the cause's stacktrace look the same.

In Squirrel I get:
{code:plain}
TEIID30504 Remote org.teiid.core.TeiidProcessingException: TEIID30504 node-one: Error on server 127.0.0.1:9997
{code}
