我已经通过 GCP Dataproc Cluster 提交了 Sqoop 作业并将其设置为--as-avrodatafile配置参数，但它失败并出现以下错误：

没有指定--as-avrodatafile参数它工作正常。

要解决此问题，您需要在提交作业时将mapreduce.job.classloader属性值设置为：true

gcloud dataproc jobs submit hadoop --cluster="${CLUSTER_NAME}" \
    --class="org.apache.sqoop.Sqoop" \
    --properties="mapreduce.job.classloader=true" \
    . . .
    -- \
    --as-avrodatafile \
    . . .
