我正在使用BAM这么多天，突然间我甚至无法做一个简单的例子（HTTPD Logs Analysis Sample），如BAM 2.0.1文档中所示。 我没有改变偏移量。
我正在采取的步骤是：
- 启动Linux中的BAM服务器
-read access.log来自$ WSO2_BAM_HOME / samples / httpd-logs / resources目录
在管理控制台中安装'HTTPD日志和分析'工具箱
现在安装时我遇到了一个hive脚本错误::
“执行Hive脚本时出错。查询返回非零代码：9，原因：失败：执行错误，从org.apache.hadoop.hive.ql.exec.DDLTask返回代码1”
你能告诉我我哪里出错吗？后端的错误是

答案 0 :(得分：0)
您能否从服务器日志中发布完整的错误跟踪？
无法在执行Hive脚本时发现错误的根本原因。查询返回非零代码：9，原因：FAILED：执行错误，从org.apache.hadoop.hive.ql.exec返回代码1。 DDLTask'，需要完整的异常跟踪来确定根本原因。
答案 1 :(得分：0)
似乎Hive无法连接到cassandra。如果您已使用任何偏移量启动BAM服务器，则casssandra端口也将更改为9160 +＆lt; port-offset＆gt;。 请用9160 +＆lt;“替换”cassandra.port“。 port-offset＆gt;。
此外，您可能需要删除Httpd_log_script中提到的Hive表，以便反映更改。这是因为，您已经运行了脚本，并且已经存储了特定表名的表定义，并且不会再尝试创建它，因为如果不存在则在脚本表中创建。（如果不是，则创建外部表）
答案 2 :(得分：0)
连接服务器似乎存在问题。你有没有更改用户名或密码？ （Dafault用户名和密码是 admin 和 admin ）
如果您使用不同的架构创建相同的现有Hive表，则必须在 CREATE .... 之前删除现有的表。 Sinthuja说道。
例如为： 删除表 table1 ，
drop table table1;
答案 3 :(得分：-1)
您可以先在BAM 2.0.1中尝试HTTPD Logs示例吗？您可以按照/samples/httpd-logs/README.txt中的说明进行操作。它运作良好。这些是该文件中给出的说明;
