Mohit Sabharwal commented on HIVE-14227:
----------------------------------------
SessionHandle is getting passed in most (all?) calls to HS2:
https://github.com/apache/hive/blob/master/service-rpc/if/TCLIService.thrift
In TThreadPoolServer
(https://github.com/apache/thrift/blob/master/lib/java/src/org/apache/thrift/server/TThreadPoolServer.java#L300)
the call order seems to be:
createContext -> processContext -> openSession (where we capture and set
sessionHandle in the context as context.setSessionHandle(sessionHandle) ->
deleteContext
Similarly, could we do for, say ExecuteStatement:
createContext -> processContext -> ExecuteStatement (where we capture and set
sessionHandle like above) -> deleteContext
IOW, you can attach the session to any connection for every request
individually. And keep a count of number of connections for every session which
you decrement in deleteContext. When it reaches 0, you can delete the session.
Am I missing something ?
