isNamespaceEnabled

public static Boolean isNamespaceEnabled(AbfsClient abfsClient,
                                         TracingContext tracingContext)
                                  throws AzureBlobFileSystemException

Return if the account used in the provided abfsClient object namespace enabled or not. It would call AbfsClient.getAclStatus(String, TracingContext).

1. If the API call is successful, then the account is namespace enabled.
2. If the server returns with HttpURLConnection.HTTP_BAD_REQUEST, the account is non-namespace enabled.
3. If the server call gets some other exception, then the method would throw the exception.

Parameters:

abfsClient - client for which namespace-enabled to be checked.

tracingContext - object to correlate Store requests.

Returns:

if the account corresponding to the given client is namespace-enabled or not.

Throws:

AzureBlobFileSystemException - throws back the exception the method receives from the AbfsClient.getAclStatus(String, TracingContext). In case it gets AbfsRestOperationException, it checks if the exception statusCode is BAD_REQUEST or not. If not, then it will pass the exception to the calling method.
