Problem description
A similar output is displayed 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.
