提交任务到spark集群，老是超时。至于超时原因，可能是计算量太大。
解决方案：提交时，加一个参数“–conf spark.network.timeout=10000000”。
spark-submit
–conf spark.network.timeout=10000000 \
自身修改如下：
–conf spark.network.timeout 1200s --conf spark.executor.heartbeatInterval=1200s --conf spark.driver.maxResultSize=4g
同时还会报出如下错误：
ExecutorLostFailure (executor 1 exited caused by one of the running tasks) Reason: Remote RPC client disassociated. Likely due to containers exceeding thresholds, or network issues. Check driver logs for WARN messages.
