   i built a cluster of prestosql with 2 nodes, 1 node coordinator, and the 
other is worker. I produced the messages with AVRO schema to a topic, and then 
using prestosql to query in my brokers. The coordinator loaded schema, read 
data and responsed to presto is fine, but worker is error, can't load generic 
schema. I tried to switch role of 2 nodes and the node of coordinator (before 
is worker being error) is worked fine, and the node of worker (before is 
coordinator being fine) is error. The result of request still work because of 
cooridnator processing all requests, not worker. How to fix that ??
   
   Coordinator load schema is fine
