我尝试在 ubuntu 桌面 12.04 中安装 Hoop。我已经安装了 hadoop-1.0.2。我的安装遵循http://cloudera.github.com/hoop/docs/latest/ServerSetup.html 我安装了 maven 3.0.4，git 箍。然而，当我这样做时，问题就来了，
hoop $ mvn clean package site assembly:single
问题是：
[FATAL] Non-parseable POM /home/pc/.m2/repository/com/sun/jersey/jersey-project/1.4/jersey-project-1.4.pom: end tag name </body> must match start tag name <hr> from line 5 (position: TEXT seen ...</center>\r\n</body>... @6:8) @ /home/pc/.m2/repository/com/sun/jersey/jersey-project/1.4/jersey-project-1.4.pom, line 6, column 8
和

我该怎么办？
我将maven更改为maven2，我做到了
rm -rf ~/.m2/repository/com/sun/jersey
rm -rf ~/.m2/repository/org/glassfish/packager
rm -rf ~/.m2/repository/jersey
正如丹尼尔·巴克蒂尔所说。但是现在又出现了新问题
