Review comment:
Thanks for bringing this up. Relook this process may have other
problems...
Current thread setManagedByFlushManager(true).
FlushThread flush a memtable and setManagedByFlushManager(false)
Current thread check tsfileProcessor.isManagedByFlushManager() return false
So, it's better to put all logs before submit(FlushThread) line 126.
