SAP Data Hub: default.Read File: failed to stat 'xxx': Bad Request

[RonaldKonijnenb]

Hi,

I managed to create a ADL (Azure Data Lake) connection to Data Hub. Data profiling works fine but when I simply want to read a file in ADL, I always get a bad request error.

Any thoughts?

Hi Ronald. Have you tried running this with the Trace activated?

Sometimes the final error message displayed is from the last wrapper process, while the trace may contain error message from the nested processes.

Hi,

was this issue resolved ?

I tried the write file operator for ADL, but it gives me "Bad Request" all the time .

The connection however returns an ok on checking and all the files are visible in the connection explorer.

The flowagent file producer will not even deploy, it gives a docker error like:

Error starting graph with handle [02982c14a7094e2cbdc0e7231e324a11]: error building docker image.

Any help is appreciated !

Hi,

Even after moving to 2.3 the issue is not fixed.

[RonaldKonijnenb]

2.3 indeed. Cool, I'm going to try that asap, tx!

Sure, please update if that works.

Hi Roland,

May i know the Data Hub version you have configured ? Hoping it is 2.3.X.

Bad request error is about the unsuccessful connection to the source system. Ideally Read File operator supports ADLS, to establish a connection to ADL please could you try "Flowagent File Producer" operator.

configuration information is available here : https://help.sap.com/viewer/29ff74dc606c41acad117003f6034ac7/2.3.latest/en-US/76e9d5c257b646f9825b06...
