在${HADOOP_HOME}\share\hadoop\yarn目录下找到hadoop-yarn-common-x.x.x.jar，然后用winRAR打开；
打开以后结构如下：
进入webapps/static/目录，然后修改yarn.dt.plugins.js；做出如下修改：
（1）给js文件中添加如下代码：
Date.prototype.Format = function (fmt) { //author: meizz var o = {"M+": this.getMonth() + 1, //月份 "d+": this.getDate(), //日 "h+": this.getHours(), //小时 "m+": this.getMinutes(), //分 "s+": this.getSeconds(), //秒 "q+": Math.floor((this.getMonth() + 3) / 3), //季度 "S": this.getMilliseconds() //毫秒 };if (/(y+)/.test(fmt)) fmt = fmt.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));for (var k in o)if (new RegExp("(" + k + ")").test(fmt)) fmt = fmt.replace(RegExp.$1, (RegExp.$1.length == 1) ? (o[k]) : (("00" + o[k]).substr(("" + o[k]).length)));return fmt;
};
function renderHadoopDate(data, type, full) {if (type === 'display' || type === 'filter') {if(data === '0'|| data === '-1') {return "N/A";}return new Date(parseInt(data)).Format("yyyy-MM-dd hh:mm:ss");}// 'sort', 'type' and undefined all just use the number// If date is 0, then for purposes of sorting it should be consider max_intreturn data === '0' ? '9007199254740992' : data;
}
