使用此配置，hive性能降低

Question

当我在hive-site.xml中添加此配置命令时，配置单元查询非常慢 任何人都可以解释为什么发生在我身上？我们如何解决它？

<property>
<name>hive.support.concurrency</name>
<value>true</value>
</property>

这是我的hive-site.xml：

<configuration>
<property>
<name>javax.jdo.option.ConnectionUserName</name>
<value>root</value>
<description>Username to use against metastore database</description>
</property>
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value></value>
<description>Username to use against metastore database</description>
</property>
<property>
<name>hive.exec.dynamic.partition.mode</name>
<value>nonstrict</value>
</property>
property>
<name>hive.enforce.bucketing</name>
<value>true</value>
</property>
