收到此错误后，我点击命令

[acadgild@localhost ~]$ hdfs dfsadmin -safemode leave
17/09/25 13:04:26 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
Safe mode is OFF

再次尝试 [acadgild@localhost ~] $ hive

但得到同样的错误并且无法打开Hive promt ..请帮帮我

Answer 1

＆＃34;名称节点处于安全模式＆＃34;意味着没有足够的数据节点报告与块报告。访问Namenode UI以找出哪些datanode 尚未报道。

或者，一个或多个datanode从本地丢失了块文件系统。你可以运行

var text = "![alt text](https://www.reduceimages.com/img/image-after3.jpg) adadw  hjagwdjh ![alt text](https://www.reduceimages.com/img/image-after2.jpg)  akjhwdhawk ![alt text](https://www.reduceimages.com/img/image-afte1r.jpg)";

console.log("FInal Result --- > " + formatText(text));

function formatText(content) {
	const regex = /!\[(.*?)\]\((.*?)\)/g;

	let m;
	var printResult = (array) => {
		content = content.replace(array[0], "<img src='" + 123 + "'>");
		return false;
	};
	
	while ((m = regex.exec(content))) {
		
		if (m.index === regex.lastIndex) {
			regex.lastIndex++;
		}
		
		printResult(m);
		console.log("After Replace " + content + "\n");
	}

	return content;
}

命令查看哪些文件已损坏

即使在Name Node Safe模式之后，我也无法启动'Hive'
