----------------------------------

             Summary: Fix misleading error message about spark.network.timeout and spark.executor.heartbeatInterval
                 Key: SPARK-26564
                 URL: https://issues.apache.org/jira/browse/SPARK-26564
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 2.4.0, 2.3.2, 2.3.1, 2.3.0
            Reporter: Kengo Seki


I mistakenly set an equivalent value with spark.network.timeout to spark.executor.heartbeatInterval and got the following error:

{code}
java.lang.IllegalArgumentException: requirement failed: The value of spark.network.timeout=120s must be no less than the value of spark.executor.heartbeatInterval=120s.
{code}

But it can be read as they could be equal. "Greater than" is more precise than "no less than".
