Azure synapse: Copy data activity completed successfully but no files were created in ADLS Gen2

Pravin007 1 Reputation point


I have a pipeline that copies data from different data sources to ADLS. We run the pipeline (copy activity) and it executes successfully and in copy activity output its shows "file written 1" but when we check that file on ADLS, there is no file.

Do you know how to solve it?

Thanks in advance!

    edge or ASA, copy data makes it exasperating to copy one DLG2 path\dataFile to another DLG2 path\dataFile DLG2.
    i have a fully functioning ASA Pipeline that should do this without issue. what i get is the source file rewritten in place, and the ASA copy data activity claiming success. but there is no success. there is no copy of the data file in the sink path as intended. source path, source file, sink path, sink file are all colocated on same ASA DLG2 data store. the only difference is source path and the sink path. they are distinctly different paths. this should not be. help from MS is requested.

    believe it or not specifying one ASA 'dataset' for source and a second distinct ASA 'dataset' for sink got me past this. spooky

    Answer must be at least 10 characters. use separate ASA datasets for source, sink. that worked for me. spooky
