rdhabalia opened a new pull request #3411: Fix race condition: broker not scheduling read for active consumer
URL: https://github.com/apache/pulsar/pull/3411
 
 
   ### Motivation
   
   Right now, `readOnActiveConsumerTask` is not thread-safe and it's being updated into different thread.  and one thread updates it to null but at the same time new active consumer gets connected on second thread then second thread will find `readOnActiveConsumerTask` non-null which avoids read-scheduling for new active consumer.
   
   ### Result
   
   It will fix possible race condition when multiple consumers try to connect to fail-over subscription.
