com.google.apphosting.api.ApiProxy $ CallNotFoundException：未找到API包“ memcache”或调用“ Get（）”

Question

I am trying to upload a file on google storage using a spring web application (currently running on my local tomcat later will deploy it on google compute engine) and getting the following exception. Tried searching on internet but did not get any solution. Any help is highly appreciated.

i have set json key downloaded from API &auth section of console and set its path in $GOOGLE_APPLICATION_CREDENTIALS environment variable. Earlier it was working i was able to upload file on a google bucket.Not it gives this exception.

com.google.apphosting.api.ApiProxy$CallNotFoundException: The API package 'memcache' or call 'Get()' was not found.

Method that gives storage service is:

/**
   * Returns an authenticated Storage object used to make service calls to Cloud Storage.
   */
  private Storage getService() throws IOException, GeneralSecurityException {
    if (null == storageService) {
      GoogleCredential credential = GoogleCredential.getApplicationDefault();
      // Depending on the environment that provides the default credentials (e.g. Compute Engine,
      // App Engine), the credentials may require us to specify the scopes we need explicitly.
      // Check for this case, and inject the Cloud Storage scope if required.
      if (credential.createScopedRequired()) {
        credential = credential.createScoped(StorageScopes.all());
      }
      HttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport();
      storageService = new Storage.Builder(httpTransport, JSON_FACTORY, credential)
          .setApplicationName(APPLICATION_NAME).build();
    }
    return storageService;
  }
  // [END get_service]

  // [START list_bucket]
  /**
   * Fetch a list of the objects within the given bucket.
   *
   * @param bucketName the name of the bucket to list.
   * @return a list of the contents of the specified bucket.
   */

Method that uploads to bucket is:

@Override
  public  void uploadStream(
      String name, String contentType, InputStream stream, String bucketName)
      throws IOException, GeneralSecurityException {
    InputStreamContent contentStream = new InputStreamContent(contentType, stream);
    StorageObject objectMetadata = new StorageObject()
        // Set the destination object name
        .setName(name)
        // Set the access control list to publicly read-only
        .setAcl(Arrays.asList(
            new ObjectAccessControl().setEntity("allUsers").setRole("READER")));

    // Do the insert
    Storage.Objects.Insert insertRequest = getService().objects().insert(
        bucketName, objectMetadata, contentStream);

    insertRequest.execute();
  }

The issue was with tomcat priviledge. If i start tomcat with root user then it works fine. If i start it with sudo it doesn't. What can i do to make it work with tomcat user with sudo priviledge.
