sijie opened a new pull request #1379: [table service] apply backoff policy to 
rpc requests if storage container is not found
URL: https://github.com/apache/bookkeeper/pull/1379
 
 
   Descriptions of the changes in this PR:
   
   *Motivation*
   
   A storage container can move between servers due to failures, or it can take 
time to start on a server. During that short period of time, it is 
"unavailable" and clients will receive `Status.NOT_FOUND` from grpc channels. 
The client should retry on this error and attempt to re-locate the storage 
container again.
   
   *Modification*
   
   - add backoff policy in client settings
   - apply the backoff policy at storage container channel. if it receives 
`NOT_FOUND` grpc exception, it will reset the server channel, so subsequent 
requests will re-attempt to relocate the storage container.
