Biswa Ranjan Ray updated JCLOUDS-1483:
--------------------------------------
Description:
Hi Team,
I set the issue type to Improvement as I'm not sure if its a bug in jclouds
library. :)
*Usecase*: Try to delete a blob (size ~ 107kb) from a swift container using
BlobStore.removBlob() api of jclouds.
*Issue*: Following exception is obtained: com.google.gson.JsonSyntaxException:
java.lang.IllegalStateException: *Expected BEGIN_OBJECT but was STRING at line
1 column 1 path $*.
*Code*: The below code snippet shows how a blob is deleted from a swift
container.
BlobStore blobStore = getBlobStoreContext();
blobStore.removeBlob(containerName, fileName);
private BlobStoreContext getBlobStoreContext() {
final Properties override = new Properties();
override.put(KeystoneProperties.KEYSTONE_VERSION, "3");
override.put(KeystoneProperties.SCOPE, "project:" +
swiftConfig.getProject());
final String credential = swiftConfig.getPassword();
final String identity = swiftConfig.getUserDomain() + ":" +
swiftConfig.getUsername();
final String authUrl = swiftConfig.getAuthUrl();
return
ContextBuilder.newBuilder(CloudProviders.PROVIDER_SWIFT.toString())
.endpoint(authUrl+"/v3")
.credentials(identity,credential)
.overrides(override)
.buildApi(BlobStoreContext.class);
}
*Debug:* Following are my observations after debugging the code.
# got the BlobStore. The blobstore type is found to be
RegionScopedSwiftBlobStore.
# stepinto blobStore.removeBlob(containerName, fileName);
at line 396 in *RegionScopedSwiftBlobStore* class, it
expects a response from *StaticLargeObjectApi* and this is where it throws the
exception. DeleteStaticLargeObjectResponse response =
api.getStaticLargeObjectApi(regionId, container).delete(name);
*Analysis*: While the api BlobStore.removeBlob fails in a Swift container, it
works fine in AWS S3 and GCS container. I also observed that if I use
*ObjectApi.delete(objectName)* instead of BlobStore.removeBlob then the blob
gets deleted from the swift container. I believe its the StaticLargeObjectApi
that's causing issue. As per the java doc of StaticLargeObjectApi, it is in
beta and still under evaluation.
Any help is highly appreciated.
Thank you.
