AWS Error Message: A conflicting conditional operation is currently in progress against this resource

I’m getting this error intermittently.

I have a program that uses the java aws sdk and loads over the 10s of thousands of small files to s3. I see this error intermittently.

Could not find any helpful answer after doing a quick search on the internet.

Note the calling program is single threaded. The underlying aws java sdk does seem to use worker threads.

Answer

I got the same error message, when I did following:

1. created a bucket – it went by default to US region (used AWSCLI)

2. realized, the bucket shall go to EU region and deleted it (used AWS console)

3. (few minutes later) tried to create the bucket, specifying the EU region

At step 3, AWS console has shown me the error message from title of your question.

So I guess, that the bucket in US was deleted, but there are possibly some synchronization processes, which are taking time. And I hope, that waiting few hours I will find the bucket name again available for creation – this time in proper (EU) region.

FIX :- Edit: About an hour later, my attempt to create the bucket (in EU region) succeeded.
