我用 CDH4 安装了 Hcatalog（在 Ubuntu 12.04 64 位上），我目前正在尝试使用 REST 访问表信息
我重新启动了 webhcat-server service webhcat-server restart。然后我在终端执行了这个，
curl http://localhost:50111/templeton/v1/ddl/database/?user.name=hive
我得到了，
{"databases":["default","testas"]}
正如预期的那样（并且正确）。
我尝试了几次并得到了相同的输出。
然后我在浏览器中尝试了同样的方法，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-

然后我回到终端并尝试，
curl http://localhost:50111/templeton/v1/ddl/database/?user.name=hive
现在不起作用，并输出
{"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？
笔记：
在 中/etc/hcatalog/proto-hive-site.xml，我javax.jdo.option.ConnectionPassword从预先存在PASSWORD的密码更改为hive.
我知道有log4j错误，但我怀疑这与此有关
