将系统更新到 HDP 2.6.5 后出现问题。我有一个包含三个节点的集群，并尝试使用 python 启动一个简单的应用程序：
from pyspark import SparkConf, SparkContext
from pyspark.sql import SQLContext, SparkSession, HiveContext
sc = SparkContext()
print sc.master
用命令
/usr/bin/spark-submit \
--master yarn \
--deploy-mode cluster \
--name 'test script' \
/opt/test/youdmp/test/script.py
它说
Exception in thread "main" java.lang.NoSuchMethodError: org.apache.hadoop.yarn.proto.YarnProtos$ResourceProtoOrBuilder.getMemory()I
at org.apache.hadoop.yarn.api.records.impl.pb.ResourcePBImpl.getMemory(ResourcePBImpl.java:61)

at org.apache.spark.deploy.SparkSubmit$.main(SparkSubmit.scala:136)
at org.apache.spark.deploy.SparkSubmit.main(SparkSubmit.scala)
当应用程序在一个或另一个节点上启动时，我可以看到这种情况。但是第三个节点有效。
客户端部署模式说：

会是怎样的错误？我应该修复什么？
似乎 Yarn 无法在某些节点上启动 Application Master，因为节点上的某些库不同。但我不知道哪些库是，两个节点都有相似的库
