apache-drill - apache钻java.lang.NullPointerException

问题描述

我正在尝试在 Windows 下以嵌入式模式使用钻。但我有以下错误：

> sqlline.bat -u "jdbc:drill:zk=local"
DRILL_ARGS - " -u jdbc:drill:zk=local"
Calculating HADOOP_CLASSPATH ...
HBASE_HOME not detected...
Calculating Drill classpath...
java.lang.NullPointerException
apache drill 1.13.0
"a drill is a terrible thing to waste"

0: jdbc:drill:zk=local>
0: jdbc:drill:zk=local>
0: jdbc:drill:zk=local> show tables;
No current connection
0: jdbc:drill:zk=local>

您可以看到当前没有连接，并且 Web 控制台也不起作用。谢谢

编辑：添加日志文件内容。

解决方案

您的 HADOOP_CLASSPATH 中有与 Drill 的不兼容的 Guava 版本。你可以在这里找到类似的问题：DRILL-4931 , DRILL-4928

尝试从您的 HADOOP_CLASSPATH 中排除 Guava jars，或者通过以下方式取消设置：
~$unset HADOOP_CLASSPATH

合并 PR for DRILL-6422后应解决此问题
