apache-drill-1.12.0"无法启动嵌入式Drillbit"和"没有当前连接错误" (Windows 10)

我在Windows 10上使用apache-drill-1.12.0。我得到了#34;没有当前连接"发送任何查询时出错。此外,应该在localhost:8047上工作的钻取Web控制台不起作用。

我在StackOverflow上搜索了许多关于正确设置JAVA_HOME环境变量以避免错误的答案。

我已正确设置了JAVA_HOME系统变量,这就是证据。

C:\Users\Dinesh>java -version
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)

C:\Users\Dinesh>javac -version
javac 1.8.0_171

C:\Users\Dinesh>echo %JAVA_HOME%
C:\Program Files\Java\jdk1.8.0_171

现在这里有以下一组错误,我正面临着在Windows 10上进行apache钻取。

apache drill 1.12.0
"a drill in the hand is better than two in the bush"
0: jdbc:drill:zk=local> SELECT version FROM sys.version;
No current connection
0: jdbc:drill:zk=local>

这里我从命令行得到的主要错误是启动嵌入式Drillbit失败:java.lang.RuntimeException:无法反序列化&#34; /tmp/drill/sys.storage_plugins/openTSDB.sys.drill& #34; (状态=,代码= 0)

答案 0 :(得分:3)

看起来您之前使用过较旧(或较新)版本的Drill,并且该版本在/tmp/drill/sys.storage_plugins/文件夹中创建了插件配置。 如果更改了任何插件配置,则用户应删除该目录以使用其他版本的Drill。

我建议您使用最新的Drill 1.13版本的Drill并清理/ tmp / drill /目录。
