我使用AngularJS创建了一个简单的应用程序.当我试图在我的网站http://demo.gaurabdahal.com/recipefinder中托管该项目时,它显示以下错误:

被禁止

您无权访问此服务器上的/ recipefinder.服务器无法读取htaccess文件,拒绝访问是安全的

但是如果我去http://demo.gaurabdahal.com/它会按预期显示"拒绝访问"消息,我已经打印过了.但是为什么它无法打开AngularJS项目"recipefinder".如果我试图在那里放一个简单的HTML应用程序,它打开就好了.

当我在github中托管它时,相同的AngularJS项目工作正常(http://gaurabdahal.github.io/recipefinder)

我无法理解什么是错的.

我刚刚从xampp下载页面下载xampp(7.0.8)并且安装没有错误但是当我在Netbeans中创建一个新项目时它只显示5.4作为最高的php版本而我拥有的是php7.我尝试使用xampp 5.6.23,但Netbeans仍然没有显示php5.6.

发生了什么？如何让Netbeans显示php7或php5.6.我有两个版本的xampp.

Elasticsearch scroll api 给了我这个错误

{
   "error": {
      "root_cause": [
         {
            "type": "parsing_exception",
            "reason": "Unknown key for a VALUE_STRING in [scroll].",
            "line": 2,
            "col": 15
         }
      ],
      "type": "parsing_exception",
      "reason": "Unknown key for a VALUE_STRING in [scroll].",
      "line": 2,
      "col": 15
   },
   "status": 400
}

我使用滚动 api 获取文档的代码是

GET index/type/_search?scroll=1m
{
    "size": 1000, 
   "query": {
      "match_all": {}
   }
}

这给了我很好的结果 "_scroll_id"

{
   "_scroll_id": "DnF1ZXJ5VGhlbkZldGNoBQAAAAAAAB1dFmJRbm9UR3h4UUFTVHFzV1dJMHpuOVEAAAAAAAAdXxZiUW5vVEd4eFFBU1Rxc1dXSTB6bjlRAAAAAAAAHV4WYlFub1RHeHhRQVNUcXNXV0kwem45UQAAAAAAAB1gFmJRbm9UR3h4UUFTVHFzV1dJMHpuOVEAAAAAAAAdYhZiUW5vVEd4eFFBU1Rxc1dXSTB6bjlR",

现在根据文档我应该这样做

我在 SO 上查看了很多答案，并且也遵循了它们，但错误仍然存​​在，我无法启动Intellijfor java。这是我的java版本

我的javac版本

javac 9-internal

当我cd进入<ide_folder>/bin并运行./idea.sh

我得到关注 error

以前，我hdfs在 a 上从 java创建目录single node cluster并且它运行流畅，但是一旦我使集群成为多节点，我就会收到此错误我得到的堆栈跟踪看起来像这样

这是 CreateDirectory 类

        String hdfsUri = "hdfs://localhost:9000/";
       //String dirName = args[0];
        String dirName=null;
      // String filename = args[1];
        String filename;

        if(args.length<=0) dirName = "ekbana"; filename = "text.csv";

I am trying to index a json file size of 128MB.But due to some reason, I am not able to index it and it shows no error , nothing. But if I break the file to two files size 50mb and 60mb or any size less than 100mb, the file is indexed. Since it gives me no error, I have no idea why I cannot index the file

I am using this command

curl -H 'Content-Type: application/x-ndjson' -XPOST 'localhost:9200/novcart/sales/_bulk' --data-binary …
