impala JDBC报错：[Simba][ImpalaJDBCDriver](500323) Error processing query translation statement.

impala JDBC连接impala表（impala和kudu关联表）进行upsert，delete操作，upsert操作没有任何问题，但是delete操作报错，完整错误如下：

删除语句是：delete from user where rowkey='1001'

我用的impala jdbc驱动是2.5.42，解决办法有两个：

1.升级驱动。当前我看的官方最新驱动版本是2.6.4，于是更新到2.6.4就不会报错了。阿里仓库里没有impala jdbc驱动，先去官网把对于版本驱动下下来，然后使用命令：

mvn install:install-file -Dfile=F:/externallib/ImpalaJDBC41-2.6.4.jar -DgroupId=com.cloudera -DartifactId=ImpalaJDBC41 -Dversion=2.6.4 -Dpackaging=jar 

 加到本地仓库，在maven中就可以正常使用了。

2.删除语句加一个分号，如下：

connection.prepareStatement("delete from user where rowkey='1001';")

算是impala的一个小bug吧。

maven配置：

<dependency>
    <groupId>com.cloudera</groupId>
    <artifactId>ImpalaJDBC41</artifactId>
    <version>2.6.4</version>
</dependency>
