wenbingshen opened a new pull request #2836:
URL: https://github.com/apache/bookkeeper/pull/2836


   ### Motivation
   
   Original PR: https://github.com/apache/bookkeeper/pull/1755,
   It should be that this PR forgot to modify the memory application method.
   
   When the direct memory is insufficient, it does not fall back to the jvm 
memory, and the bookie hangs directly.
