Symptom
The following exception occurs when I use Tablestore SDK for Java:
java.lang.IllegalStateException: Request cannot be executed; I/O reactor status: STOPPED
Cause
shutDown is called to shut down the OTSClient instance and the internal I/O reactor. If the OTSClient instance is called to read and write data, the error occurs.
Solution
Check whether the OTSClient instance is shut down. If the OTSClient instance is shut down, reinitialize the OTSClient instance.
