i have issue when i tryin to migrate simple file from s3 to HDFS (onprimes) with AWS DataSync agent.

aws side error:

Transfer and verification completed. Verification detected mismatches. Files with mismatches are listed in Cloud Watch Logs

cloudwatch:

[ERROR] Deferred error: s3:c96 close("/data/test/datasync//test.txt"): 5 (Input/output error)

HDFS name node log:

java.io.IOException: File /data/test/datasync/test.txt could only be written to 0 of the 1 minReplication nodes. There are 6 datanode(s) running and 6 node(s) are excluded in this operation.

Hello @Vako

You may require further investigation from the AWS support team concerning this:

[ERROR] Deferred error: s3:c96 close("/data/test/datasync//test.txt"): 5 (Input/output error)

This error comes from S3 protocol, also this message from NN logs:

java.io.IOException: File /data/test/datasync/test.txt could only be written to 0 of the 1 minReplication nodes. There are 6 datanode(s) running and 6 node(s) are excluded in this operation.

This means that the client reached the Namenode, so it wrote the file at metadata level in HDFS, but when the application tried to write the data to the different datanodes this fails for some reason, maybe you can check if Datanode's logs tell you something at the time of the issue, but I've always seen this issue caused by some problem/misconfiguration in the application side, also you can validate if there are no firewall rules blocking the datanode port for the server where you are running this AWS DataSync agent.

Hope this helps.

@blizano thank your reply.

I checked and there is no any firewall rule or network port block.

do u have any idea?
