Description

Events are not written to file when the queue becomes full, and it ignores the post_exec_hook / pre_exec_hook event. The default capacity is 64 in hive.hook.proto.queue.capacity config for hs2.

Now, we will increase the queue-capacity (let's say upto 256).
Also for the optimisation, need to run all the events present in a task_queue, and write in a single file.
