我正在与apache airflow 1.8.0.

这是我backfill工作时的输出。

我有以下表格,我想发布到page.php,并希望在page.php上获得结果,并希望使用AJAX或JQUERY在表格框中显示数据,这可能吗？如果是,请告诉我.我不想刷新页面,因为我想填充单页上的所有数据,并希望在该页面上显示所有结果(IN表格单元格作为一个表中的用户输入数据,它将更新其响应).

<form method = "post" action = "page.php">
    <input type = "text" name = "fld1" id = "fld1" />
    <input type = "text" name = "result1" id = "result1" value = "value_from_php_page" disabled />
    ...
</form>

我正在尝试实现 Ajax Loader。加载时，它会使背景模糊，这很好，但背景内容仍然处于活动状态。我希望在加载程序出现时禁用背景。

CSS

.container{
        /* overflow: hidden; */
    -webkit-filter: blur(13px);
    -moz-filter: blur(13px);
    -o-filter: blur(13px);
    -ms-filter: blur(13px);
    filter: blur(13px);
}
#spinner
{
    /* display: none; */
    width:100px;
    height: 100px;
    position: fixed;
    top: 50%;
    left: 50%;
    background:url(../loading.gif) no-repeat center transparent;
    text-align:center;
    padding:10px;
    margin-left: -50px;
    margin-top: -50px;
    z-index:2;
    overflow: auto;
}

HTML

<div id="spinner"></div>
<div class="container">
    <!-- Some buttons and links are here, I want these disabled(container gone blurred but links and buttons are still active)-->
</div>

运气好的话？

我正在 CentOS 上工作，我已经设置$SPARK_HOME并添加了binin的路径$PATH。

我可以pyspark从任何地方逃跑。

但是当我尝试创建python文件并使用此语句时；

from pyspark import SparkConf, SparkContext

它抛出以下错误

python pysparktask.py
    Traceback (most recent call last):
    File "pysparktask.py", line 1, in <module>
      from pyspark import SparkConf, SparkContext
    ModuleNotFoundError: No module named 'pyspark'

我尝试使用 再次安装它pip。

pip install pyspark

它也给出了这个错误。

找不到满足 pyspark 要求的版本（来自版本：）没有找到 pyspark 的匹配发行版

编辑

根据答案，我更新了代码。

错误是

Traceback (most recent call last):
  File "pysparktask.py", line 6, in <module>
    from pyspark import SparkConf, SparkContext
  File "/opt/mapr/spark/spark-2.0.1/python/pyspark/__init__.py", line 44, …

我跟着代码

<div class="container">
    <div class="row">
        <nav class = "navbar navbar-inverse navbar-fixed-top">
            <div class="navbar-header">
                <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#topMenu" aria-expanded="false" aria-controls="navbar">
                    <span class="sr-only">Toggle navigation</span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                </button>
                <a class="navbar-brand" href="#">Brand</a>
            </div>
            <div class = "collapse navbar-collapse" id = "topMenu">
                <ul class="nav navbar-nav navbar-right">
                    <li><a href="#" class = 'navAnchor'>Link</a></li>
                    <li><a href="#" class = 'navAnchor'>Link</a></li>
                    <li><a href="#" class = 'navAnchor'>Link</a></li>
                    <li><a href="#" class = 'navAnchor'>Link</a></li>
                </ul>
            </div><!-- /.navbar-collapse -->
        </nav>
    </div>
</div>

我也试图改变

<div class = "collapse navbar-collapse" …
