Description

Hello, I am getting a weird behavior from swift api client. The scenario is: I have a blobStore object, invoking blobStore.createContainerInLocation(location, container) works well but checking container exists before creating container, then use that blobStore to get a blob throws an exception:

 

blobStore.createContainerInLocation(location, container); 
blobStore.getBlob(container, blobId); // works well

blobStore.containerExists(container);
blobStore.createContainerInLocation(location, container); 
blobStore.getBlob(container, blobId); // throws here

This is a part of stack trace:

java.lang.IllegalStateException: Optional.get() cannot be called on an absent value

 at com.google.common.base.Absent.get(Absent.java:43)
 at org.jclouds.openstack.swift.v1.blobstore.RegionScopedSwiftBlobStore.toBlobMetadata(RegionScopedSwiftBlobStore.java:607)

 at org.jclouds.openstack.swift.v1.blobstore.RegionScopedSwiftBlobStore.getBlob(RegionScopedSwiftBlobStore.java:374)

Is it a bug or an expected behavior? Or if it is expected, could you explain the reason why exception thrown, Thanks!

I'm using an docker to run openstack swift which is using:

• keystone 12.0.0
