You can configure Hadoop accounts in SnapLogic using either the Designer or Manager.
Using SnapLogic Designer
Selecting an existing account
SnapLogic organizes and displays all accounts to which you have access, sorting them by account type and location. To select an existing account:
Click the icon to view the accounts to which you have access and select the account that you want to use.
Click.
Creating an account
Click Add Accountin theAccount Referencedialog.
Select theLocationin which you want to create the account, select the account type, and clickContinue. TheAdd Accountdialog associated with the account type appears.
Enter the required account details. For detailed guidance on how to provide information associated with each account type, use the following links:
Enter additional information on this account in the Notes field of the Info tab. This will help you–and other users–understand the purpose of the account, especially if there are multiple accounts of the same type.
Click Validate to verify the account, if the account type supports validation.
Click Apply to complete configuring the binary account.
Using SnapLogic Manager
UseManagerto create accounts without associating them immediately with Pipelines.
Accounts in SnapLogic are associated with projects. You can use accounts created in other projects only if you have at least Read access to them.
In the left pane, browse to the project in which you want to create the account and click Create > Account > Binary, followed by the appropriate account type.
The Create Account dialog associated with the selected account type appears.
Repeat the steps numbered 3 through 5 in the previous section.
Avoid updating account credentials while Pipelines using that account are executing. This may lead to unexpected results, including locking your account.

The upgrade of the Azure Storage library from v3.0.0 to v8.3.0 has impacted the Hadoop Snap Pack causing the following issue when using the WASB protocol.
Known Issue
When you use invalid credentials for the WASB protocol in Hadoop Snaps (HDFS Reader, HDFS Writer, ORC Reader, Parquet Reader, Parquet Writer), the pipeline does not fail immediately, instead it takes 13-14 minutes to display the following error:
reason=The request failed with error code null and HTTP code 0. , status_code=error
SnapLogic® is actively working with Microsoft®Support to resolve the issue.
Fixed a resource leak issue with the following Hadoop Snaps, which involved too many stale instances of ProxyConnectionManager and significantly impacted memory utilization.
Enhanced the HDFS Writer Snap with the Write empty file checkbox to enable you to write an empty or a 0-byte file to all the supported protocols that are recognized and compatible with the target system or destination.
