   Hi @zhouyuan , I found a case where the reader times out even when 
`failOnDataLoss=false`. If Spark plans to read 100 messages but Kafka’s log 
gets truncated to 10, the reader reads those 10 and then keeps waiting for the 
rest.
   
   I’ve prepared a fix so it finishes with the available data when data loss is 
allowed, and reports data loss otherwise. It also checks that an open 
transaction isn’t being mistaken for truncation
