Just realized that adding one more empty line will fix it. Will make the

> Key: GOBBLIN-963
> URL: https://issues.apache.org/jira/browse/GOBBLIN-963
> Project: Apache Gobblin
> Issue Type: Bug
> Reporter: Chen Guo
> Priority: Major
> Time Spent: 50m
> Remaining Estimate: 0h
>
> Currently in GobblinMultiTaskAttempt, when we call createTaskRunnable, we
> rely on a TaskFactory to create a task and return a wrapper for that task.
> However, when we create the wrapper, we initialized the TaskContext twice.
> # For the task creation
> # For the task wrapper creation
> These two TaskContexts, which generate two copies of TaskState, will cause
> inconsistency in the following operation. The task state update within the
> task won't be reflected in TaskWrapper.
>
> Specifically, this is the buggy line of code
> {code:java}
> return new TaskIFaceWrapper(taskFactoryOpt.get().createTask(new
> TaskContext(workUnitState)),
> new TaskContext(workUnitState), countDownLatch, this.taskStateTracker);
> {code}
> Ideally, we should create the TaskContext once, and reuse the same
> TaskContext.
