> In RpcRetryingCallerImpl:
> {code}
> public T callWithRetries(RetryingCallable<T> callable, int callTimeout)
> throws IOException, RuntimeException {
> ...
> for (int tries = 0;; tries++) {
> try {
> ...
> return callable.call(getTimeout(callTimeout));
> ...
> } catch (Throwable t) {
> ExceptionUtil.rethrowIfInterrupt(t);
> if (tries > startLogErrorsCnt) {
> LOG.info("Call exception, tries=" + tries + ", maxAttempts=" +
> maxAttempts + ", started="
> + (EnvironmentEdgeManager.currentTime() -
> tracker.getStartTime()) + " ms ago, "
> + "cancelled=" + cancelled.get() + ", msg="
> + callable.getExceptionMessageAdditionalDetail());
> }
> ...
> {code}
> We log the callable.getExceptionMessageAdditionalDetail() msg. But
> callable.getExceptionMessageAdditionalDetail() may not provide the underlying
> cause..
> For example, in AbstractRegionServerCallable,
> {code}
> public String getExceptionMessageAdditionalDetail() {
> return "row '" + Bytes.toString(row) + "' on table '" + tableName + "' at
> " + location;
> }
> {code}
> Let's add the underlying exception cause to the message as well.
