Question

我正在尝试在Oracle Linux 7上设置HDP 3.1.0。

Ambari，HDFS和HIVE Metastore服务已经在运行，但是HiveServer2没有启动。

当我尝试手动启动它时：

# hive --service hiveserver2

等待几分钟后我得到了：

这是netstat报告的内容：

# netstat -ntpl | egrep "10000|10001|10002"
tcp        0      0 192.168.1.100:10001     0.0.0.0:*               LISTEN      422/java

没人在端口10000上监听：（

这是我在/hive-site.xml中拥有的内容：

<property>
  <name>hive.server2.thrift.port</name>
  <value>10000</value>
</property>
<property>
  <name>hive.server2.thrift.http.port</name>
  <value>10001</value>
</property>
<property>
  <name>hive.server2.webui.port</name>
  <value>10002</value>
</property>

我认为我可以忽略SLF4J警告，对吗？我还应该检查什么？

Answer 1

事实证明，此服务试图获取的内存超过默认 /etc/hadoop/conf/yarn-site.xml 设置允许的1024 MB：

<property>
  <name>yarn.nodemanager.resource.memory-mb</name>
  <value>1024</value>
</property>

我将该限制提高到1792，问题得到解决。
