merlimat opened a new pull request #1203: Use duplicates when writing from ByteBuf pair to avoid multiple threads issues
URL: https://github.com/apache/incubator-pulsar/pull/1203
 
 
   ### Motivation
   
   This is a fix for #1201.
   
   The truncation happens when, during an unload, the topic moves from one broker to another. If the write operation on the previous connection was still ongoing, it can cause issues when the new IO (associated with the "new" connection) will start writing on the new socket.
   
   ### Modifications
   
   Take a duplicate of the`ByteBuf` so that each thread will have its own `readerIndex` on the buffer.
