   … on multiple BEs
   
   ## Proposed changes
   Since projection pushdown requires knowing the schema information of the 
avro file in advance.
   In the previous implementation, avro schema information was cached in be. 
   When there are multiple BEs in the cluster, the other BEs cannot obtain the 
avro schema, resulting in a NullPointerException.
