請各位大牛幫忙：
這幾天剛接觸linux和hadoop.在安裝hadoop時配置core-site.xml檔案時沒發現問題，但是格式化時提示core-site.xml配置錯誤。下面是core-site.xml的組態檔：
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="https://bbs.csdn.net/topics/configuration.xsl"?>

</property>
<property>
<name>hadoop.tmp.dir</name>

<configuration>
下面是編譯錯誤的提示：
