在 Dremio 中运行这个简单的查询时：

SELECT 'NBC Universal – NBC News' Data

我们收到以下错误消息

Failed to encode 'NBC Universal – NBC News' in character set 'ISO-8859-1'

我们尝试使用以下 docker 命令为字符集设置 saffron 设置：

docker run -p 9047:9047 -p 31010:31010 -p 45678:45678 -e DREMIO_JAVA_SERVER_EXTRA_OPTS="-Dcalcite.default.charset=UTF-16LE -Dcalcite.default.nationalcharset=UTF-16LE -Dcalcite.default.collation.name=UTF-16LE$en_US"  dremio/dremio-oss

Dremio 版本是 4.1

是否有任何配置可以使 Dremio 默认字符集为 UTF-8 或 UTF16 ？

我们正在查看此线程以了解如何在 Dremio 中配置字符集。

The issue was that $ in the calcite config has to be escaped, and also since Dremio (4.1) is still using calcite 1.16 , saffron config needs to be saffron.default instead of calcite.default. 

docker run -p 9047:9047 -e DREMIO_JAVA_SERVER_EXTRA_OPTS="-Dsaffron.default.charset=UTF-16LE -Dsaffron.default.nationalcharset=UTF-16LE -Dsaffron.default.collation.name=UTF-16LE\$en_US" dremio/dremio-oss:4.1.7

For direct fix in Dremio config files, dremio-env file needs to updated with this:

# Extra Java options - server only (dremio command)
#
DREMIO_JAVA_SERVER_EXTRA_OPTS="-Dsaffron.default.charset=UTF-16LE -Dsaffron.default.nationalcharset=UTF-16LE -Dsaffron.default.collation.name=UTF-16LE\$en_US"
