Error description

  • When you have a mart with a dimension table with many rows and
    several worker nodes are defined there exists a possibility that
    a dropPartMart() operation on this dimension table fails with an
    assertion like
    
    <?xml version="1.0" encoding="UTF-8" ?> <dwa:messageOutput
    xmlns:dwa="http://www.ibm.com/xmlns/prod/dwa" version="1.0">
    <message severity="error" reason-code="AQT10050I"><text>An
    internal error occurred on the 'ACC1' accelerator: An assertion
    'activeRows == expectedRows' failed. Additional info: Found 0
    rows with epoch 2 in table "informix"."tab1" where 650000000 - 0
    - 27962143607091 = 18446716112215944525 rows were
    expected</text></message></dwa:messageOutput>
    
    The total number of rows in this table is 6.5 * 10^8 and the
    number of worker nodes is 5.
    

Local fix

  • A possible work around to this situation can be to reduce the
    number of worker nodes. Please be aware that every dimension
    table will be distributed to every worker node.
