解决方案：
1、在Catalog中Properties修改hudi.properites
hive.config.resources=/etc/hadoop/conf/core-site.xml, /etc/hadoop/conf/hdfs-site.xml,/opt/presto-server/etc/catalog/hdfs-site.xml
2、编辑/opt/presto-server/etc/catalog/hdfs-site.xml
<configuration xmlns:xi="http://www.w3.org/2001/XInclude">
<property>
<name>dfs.client.use.legacy.blockreader</name>
<value>false</value>
</property>
</configuration>
3、重启presto
