We have recently introduced a new requirement - when an HTTP retrieval succeeded, the checker is required to test HEAD retrieval request too. The preprocessing step in spark-evaluate discards measurements missing `head_status_code`. Because a large part of the network is running an older version of Spark Checker, measurements from these nodes are rejected as invalid. See CheckerNetwork/spark-evaluate#498. This patch is moving the validation step earlier to the pipeline by changing the minimum required Spark Checker version to 1.17.0. Checker nodes running an older version will start receiving a helpful "OUTDATED CLIENT" error response. Signed-off-by: Miroslav Bajtoš <[email protected]>
