FAILED: SemanticException Failed to get a spark session: org.apache.hadoop.hive.ql.metadata.HiveException: Failed to create Spark client due to invalid resource request: Required executor memory (2048), overhead (384 MB), and PySpark memory (0 MB) is above the max threshold (2048 MB)

解决方案
在hadoop中/etc/hadoop/yarn-site.xml添加

 <!-- yarn容器允许分配的最大最小内存 -->
    <property>
        <name>yarn.scheduler.minimum-allocation-mb</name>
        <value>512</value>
    </property>
    <property>
        <name>yarn.scheduler.maximum-allocation-mb</name>
        <value>4096</value>
    </property>
    
    <!-- yarn容器允许管理的物理内存大小 -->
    <property>
        <name>yarn.nodemanager.resource.memory-mb</name>
        <value>4096</value>
    </property>
    
    <!-- 关闭yarn对物理内存和虚拟内存的限制检查 -->

        <name>yarn.nodemanager.pmem-check-enabled</name>
        <value>false</value>
