<p>This is an implementation that follow {@link java.nio.file.Files#readAllBytes(java.nio.file.Path)},
and the difference is that it limits the size of the direct buffer to avoid
direct-buffer OutOfMemoryError. When {@link java.nio.file.Files#readAllBytes(java.nio.file.Path)}

Since {@link SparkLauncher} runs {@code spark-submit} in a sub-process, it's difficult to
accurately retrieve the full {@link Throwable} from the {@code spark-submit} process.
This method parses the logs of the sub-process and provides a best-effort attempt at
returning the last exception thrown by the {@code spark-submit} process. Only the exception
message is parsed, the associated stacktrace is meaningless.
