APEXCORE-505 Heartbeat loop was blocked waiting for operator activati⦠â¦on, the reason for this is that Stream activation(Only BufferServerSubscriber and WindowGenerator) waits for operator activation in a heartbeat thread. There is no need to have this synchronization, as Tuples are pulled from the queues by the operators. @vrozov @tweise please review You can merge this pull request into a Git repository by running: $ git pull https://github.com/sandeshh/apex-core APEXCORE-505 Alternatively you can review and apply these changes as the patch at: https://github.com/apache/apex-core/pull/405.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #405 ---- commit 596b996b1aa694bb9a0924f9094ef688df23678e Author: Sandesh Hegde <sandesh.he...@gmail.com> Date: 2016-10-05T01:29:57Z APEXCORE-505 Heartbeat loop was blocked waiting for operator activation, reason for this is that Stream activation(Only BufferServerSubscriber and WindowGenerator) waits for operator activation in heartbeat thread.
