如何在hdfs中保存namenode信息(How to persist namenode information in hdfs)

我在桌面上设置了一个单节点集群。 问题是我不能让我的桌面一直运行。 我执行stop-all.sh,稍后当我执行start-all.sh时,我的namenode没有启动。 最后我必须做%hadoop namenode -format,继续通过丢失我的所有数据。


I have setup a single node cluster on my desktop. Problem is i can't keep my desktop running all the time. I do perform stop-all.sh, still later on when i perform start-all.sh , my namenode doesn't start up. And finally i have to do %hadoop namenode -format , to continue there by loosing all my data.

最满意答案

.graph-placeholder min-height设置为合理的绝对值,如100px

我还建议为可调整大小的容器设置最小值和最大值(请参见此处 )。


My whole fix is a bit hacky but it works. I first set the height to be the same as the containers

 $("#ResizableContainer").show();
    if ($("#placeholderForGraph").height() === 0) {
        $("#placeholderForGraph").css('min-height', $("#ResizableContainer").height()); 
    }
    plot = $.plot($("#placeholderForGraph"), []); 

And then fill out the graph with data and options of my choice and after that i change the style og the placeholder:

 $("#placeholderForGraph").css('min-height', "100px");
 $("#placeholderForGraph").css('height', "100%");
 $("#placeholderForGraph").css('width', "100%"); 

Big thanks to @Raidri for help :)
