描述
```java
public InternalColumnEncryptionSetup getColumnSetup(ColumnPath columnPath,
boolean createIfNull, int ordinal) {
InternalColumnEncryptionSetup internalColumnProperties = columnMap.get(columnPath);
if (null != internalColumnProperties) {
if (ordinal != internalColumnProperties.getOrdinal()) {
throw new ParquetCryptoRuntimeException("Column ordinal doesnt match " + columnPath +
": " + ordinal + ", "+internalColumnProperties.getOrdinal());
}
return internalColumnProperties;
}
------ here is always true, then throw Exception
if (!createIfNull) {
throw new ParquetCryptoRuntimeException("No encryption setup found for column " + columnPath);
}
if (fileCryptoMetaDataCreated) {
throw new ParquetCryptoRuntimeException("Re-use: No encryption setup for column " + columnPath);
}
```

调研方向
首先跟踪 getColumnSetup(ColumnPath, boolean, int) 以及 issue 中所示的 columnMap 查找。重现 createIfNull 检查导致异常的已报告路径,然后验证在该情况下加密整个表不再失败。
由索引模型根据 Issue 内容生成。
