Hadoop fs -get仅复制特定文件(Hadoop fs -get copy only specific files)

 有没有办法只复制特定文件，比如根据文件类型使用fs -get或fs -copyToLocal？ 注意：我希望这是递归的并遍历整个集群。  
 想出来但我不能回答我自己的问题。  
 这是我们如何做到的。 刚写了一个快速的shell脚本。  
mkdir /tmp/txt

    for F in `hadoop fs -fs hdfs://namenode.mycluster -lsr / | grep '/*.txt$' | awk '{print $NF}'; 
    do
       hadoop fs -fs hdfs://namenode.mycluster -copyToLocal $F /tmp/las/ 
    done

Is there a way to copy only specific files, say based on file type using fs -get or fs -copyToLocal? Note: I would like this to be recursive and traverse the entire cluster. 
Figured it out but I can't answer my own question.  
Here's how we did it. Just wrote a quick shell script.  
mkdir /tmp/txt

    for F in `hadoop fs -fs hdfs://namenode.mycluster -lsr / | grep '/*.txt$' | awk '{print $NF}'; 
    do
       hadoop fs -fs hdfs://namenode.mycluster -copyToLocal $F /tmp/las/ 
    done

 尝试从<li>删除inline显示，然后使用float:left 。  
 试一试： http ： //jsfiddle.net/RGvjj/1/  
#navigation li {
    font-size: 20px;
    margin-left: 10px;
    padding-left: 10px;
    border-left: 3px solid #1161A5;
    color: #ffffdd;
    text-decoration: none;
    float:left;
}
 
 
 编辑：为了解释，我猜这种情况正在发生，因为当您为元素设置动画时，jQuery会将display更改为block 。 所以你最终得到一个内inline元素（ <li> ）中的block元素（ <a> ），它不起作用。  
 通过使用float:left ， <li>保留其block显示，这使得<a>成为block有效。 

Try removing the inline display from the <li> and use float:left instead. 
Try it out: http://jsfiddle.net/RGvjj/1/ 
#navigation li {
    font-size: 20px;
    margin-left: 10px;
    padding-left: 10px;
    border-left: 3px solid #1161A5;
    color: #ffffdd;
    text-decoration: none;
    float:left;
}
 
 
EDIT: To explain, I'm guessing this is happening because when you animate an element, jQuery changes the display to block. So you were ending up with a block element (the <a>) inside an inline element (the <li>) which doesn't work.  
By using float:left, the <li> retains its block display, which makes it valid for the <a> to be block.
