Hadoop 使用Hcatalog REST从配置单元访问表

我在Ubuntu12.04 64位上安装了带有CDH4的Hcatalog，目前我正在尝试

我重新启动了webhcat服务器服务webhcat服务器重新启动。 然后我在终点站做了这个

curl http://localhost:50111/templeton/v1/ddl/database/?user.name=hive

我得到了

{"statement":"show databases like '*';","error":"unable to show databases for: *","exec":
{"stdout":"","stderr":"Hive history file=/tmp/hive/hive_job_log_9f5d4411-e8f4-4c7e-a8db-
3bc53a565db8_2034639464.txt\nSLF4J: Class path contains multiple SLF4J bindings.\nSLF4J:

{数据库：[默认，测试]}

正如预期和正确的

我试了几次，得到了同样的结果

然后我在浏览器中尝试了同样的方法

{"statement":"show databases like '*';","error":"unable to show databases for: *","exec":
{"stdout":"","stderr":"Hive history file=/tmp/hive/hive_job_log_9f5d4411-e8f4-4c7e-a8db-

1.6.1.jar!/org/slf4j/impl/StaticLoggerBinder.class]\nSLF4J: See

然后我回到终点站试着

curl http://localhost:50111/templeton/v1/ddl/database/?user.name=hive

现在不起作用，输出

{"statement":"show databases like '*';","error":"unable to show databases for: *","exec":
{"stdout":"","stderr":"Hive history file=/tmp/hive/hive_job_log_ce3f8d69-35b1-4617-b3a5-

为什么会这样

注:

在/etc/hcatalog/proto-hive-site.xml中，我将javax.jdo.option.ConnectionPassword从预先存在的密码更改为hive的密码

我知道有一个log4j错误，但我怀疑这与此有关

可能是因为您的类路径中有许多版本不同的slf4j jar。这是运行java程序时引发的常见错误。有关详细信息，请检查配置单元日志配置单元历史文件。请尝试删除不必要的JAR版本。

您好，VusP，我也面临同样的问题，您有没有找到解决方案？@MukeshS Nothing当前没有。从那以后我再也没有尝试过。当我再试一次时，我会把它贴在这里。
