What problem does this PR solve?

Related PR: #42950

Problem Summary:

PR #42950 change some logic in ExportJob, by removing the taskIdToExecutor, which is
a thread safe ConcurrentHashMap.
But there is a problem that, when cancelling a export job, it will clear the jobExecutorList in ExportJob,
and meanwhile, this jobExecutorList may being traversed when creating the export job,
causing concurrent modification exception.

This PR fix it by locking the writeLock of ExportMgr when cancelling the export job.
