Field Detail

START_LOG_ERRORS_AFTER_COUNT_KEY
```
public static final String START_LOG_ERRORS_AFTER_COUNT_KEY
```
Configure the number of failures after which the client will start logging. A few failures is fine: region moved, then is not opened, then is overloaded. We try to have an acceptable heuristic for the number of errors we don't log. 5 was chosen because we wait for 1s at this stage.
