Description

The handling of default query options for erasure-coded files in custom cluster tests is brittle and breaks if custom cluster tests set their own default query options:

    if os.environ.get("ERASURE_CODING") == "true":
      cmd.append("--impalad_args=--default_query_options=allow_erasure_coded_files=true")

This was one of test failures that caused IMPALA-1760 to be reverted.
