cp seaweedfs-hadoop2-client-1.5.6.jar /opt/presto-server-347/plugin/hive-hadoop2/
```

modify /opt/presto-server-347/etc/catalog/core-site.xml to support SeaweedFS, 30888 is the filer port

<configuration>
<property>
<name>fs.defaultFS</name>
<value>seaweedfs://10.0.100.51:30888</value>
</property>
<property>
<name>fs.seaweedfs.impl</name>
