ADF can not parse Parquet files

Question

I have a pipeline that consist copy data activity like following;

I installed OpenJDK on all servers where we use our Integration Runtime. But still, I get error like the following;

 {  
        "errorCode": "2200",  
        "message": "ErrorCode=JreNotFound,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=Java Runtime Environment cannot be found on the Self-hosted Integration Runtime machine. It is required for parsing or writing to Parquet/ORC files. Make sure Java Runtime Environment has been installed on the Self-hosted Integration Runtime machine.,Source=Microsoft.DataTransfer.Richfile.ParquetTransferPlugin,''Type=System.DllNotFoundException,Message=Unable to load DLL 'jvm.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E),Source=Microsoft.DataTransfer.Richfile.HiveOrcBridge,'",  
        "failureType": "UserError",  
        "target": "Copy data1",  
        "details": []  
    }  

It seems Integration Runtime can not detect OpenJDK files, I wonder, should I install Oracle JDK instead of OpenJDK?

Answer 1

if your using the SHIR
you need jre 8 to read or write to parquet - this is a basic install for the functionality

if openjdk then there is some updating needed - follow -
