> I've noticed that three tests from {{PostgresqlImportTest}} has been failing consistently in my environment (with variously patched Hadoop version):
> * {{testDifferentSchemaImport}}
> * {{testJdbcBasedImport}}
> * {{testTableNameWithSpecialCharacter}}
> Further investigation has showed that the {{PostgresqlImportTest}} is verifying output by checking one specific file output whereas in my environment Hadoop output consisted of two files instead. Hence the tests were confused and were reporting missing rows. I feel that the fix is simple in this case - since we are expecting one output file, we should specify {{-m 1}} as parameter to force one single mapper.
