Description

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.
