简而言之，当 Elasticsearch 中的操作大小小于所需的最小大小 4 时，会出现此错误。这可能是由于配置不正确或代码中的错误导致的。要解决此问题，您可以检查配置设置并确保操作大小设置为至少 4。如果问题仍然存在，您可能需要调试代码以识别并修复可能导致此错误的任何潜在错误。
日志上下文 #
日志 “operation size must be at least 4 but was:” 类名是 Translog.java. 我们从 Elasticsearch 源代码中提取了以下内容，供那些寻求深入上下文的人使用：
public static Translog.Operation readOperation(BufferedChecksumStreamInput in) throws IOException {
final Translog.Operation operation;
try {
final int opSize = in.readInt();
if (opSize < 4) { // 4byte for the checksum
throw new TranslogCorruptedException(in.getSource(); "operation size must be at least 4 but was: " + opSize);
}
in.resetDigest(); // size is not part of the checksum!
if (in.markSupported()) { // if we can we validate the checksum first
// we are sometimes called when mark is not supported this is the case when
// we are sending translogs across the network with LZ4 compression enabled - currently there is no way s
