使用镶木地板工具打开镶木地板文件时出错
Error while opening parquet files using parquet-tools
我正在尝试使用 parquet-tools 在我的 mac 上读取一个 parquet 文件。
这是我正在使用的命令-
parquet-tools head -n 2 test.snappy.parquet
我收到以下错误-
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.apache.hadoop.security.authentication.util.KerberosUtil (file:/usr/local/Cellar/parquet-tools/1.10.0/libexec/parquet-tools-1.10.0.jar) to method sun.security.krb5.Config.getInstance()
WARNING: Please consider reporting this to the maintainers of org.apache.hadoop.security.authentication.util.KerberosUtil
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release
不确定我做错了什么?
这只是一个警告,不是错误。这是 Java 9+ 中模块系统添加的新限制。当我使用 parquet-tools 时,我看到了同样的事情。您可以放心地忽略它!
