Datameer X 11.2.5

Improvements

1	Security: Upgrade Jetty to version 9.4.50	DAP-42458
	Datameer is moved to the Jetty version 9.4.50 in order to ensure the services are not vulnerable to any known vulnerabilities.

Bug Fixes

1	Security: Penetration tests - GetFiles metadata, get the folder content via the folder ID	DAP-42468
	A user is not allowed to view any metadata for a directory without proper access (sees no folder path or file ID).	Bug fixed.

2	Security: Penetration tests - Any user may not see others schema log	DAP-42469
	A user is not allowed to see the parsing records from the artifacts created by other users.	Bug fixed.

3	Security: Penetration tests - The '/browser/list-file' endpoint returns metadata for any file in the system	DAP-42470
	A user is not allowed to view artifacts metadata without having at least a 'View' permission for these items.	Bug fixed.

4	Security: Penetration tests - Dependency graph information doesn't check the permission authorization	DAP-42471
	A user is not allowed to load an artifact’s dependency graph without having at least a 'View' permission for this item.	Bug fixed.

5	Security: Penetration tests - detailed error messages displayed	DAP-42472
	Only generic error messages without error details are now returned to Datameer users. Stack traces are logged server-side and only accessible by developers or administrators. The associated property handles the error messages.	Bug fixed.

6	Security: Penetration tests - "/rest/user-management/authenticable-users" should return list of usernames belonging to the same role only with CHANGE_FOLDER_OWNER capability	DAP-42473
	Only user who belong to the same role with the 'change folder owner' capability can view other user names from the REST API call.	Bug fixed.

Datameer X 11.2.4

Improvements

1	Drivers: Update Redshift Native JDBC driver to use Amazon's JDBC42 driver	DAP-42443
	Since the Amazon Redshift Native JDCB driver is deprecated. Therefore the the new drive should be updated to the Amazon Redshift JDBC42 driver.

Bug Fixes

1	Plugins: plugin-hbase+cdh-7.1.7.0 - Import fails	DAP-42440
	Setting the property 'hbase.server.sasl.provider.extras=org.apache.hadoop.hbase.security.provider.GssSaslClientAuthenticationProvider' bypasses the service loader lookup code with providing authentication providers.	Bug fixed.

Datameer X 11.2.3

Improvements

1	Importing Data: Add an option to configure the default value for "Records for Schema Detection"	DAP-42421
	The new custom property 'das.conductor.default.record.sample.size' controls what 'Records for schema detection' value is set by default whenever a user creates a new Import Job, Data Link or File Upload. It should be adjusted, e.g. when working with large JSON objects (should be decreased to 250 - 500). Once updated, it affects only newly created Import Jobs, the 'Records for schema detection' value for existing artifacts remains intact.

Bug Fixes

1	Export: Snowflake - Exporting to a new table leads to duplicated columns error intermittently	DAP-42012
	After fixing the plug-in, the export sheet can be executed without any errors again.	Bug fixed.

2	Export: Snowflake - Intermittent Export failure, insert value list does not match the column list	DAP-42442
	After a plug-in fix, the columns list now matches the insert value list as expected again.	Bug fixed.

	The timeout in a S3A filesystem can be changed via the properties 'fs.s3a.connection.establish.timout' and 'fs.s3a.connection.timeout' now in order to prevent job timeouts.

Bug Fixes

1	Security: Spring framework CVE vulnerabilities	DAP-42402
	The user has been backported to Spring framework 4.3.	Bug fixed.

2	Plug-ins: Plugin Parquet - Datameer encodes DATE values in base64 while exporting into a Parquet file	DAP-42382
	After the 'plugin-parquet' was patched, the DATE fields are exported correctly.	Bug fixed.

3	Export: Tableau - Hyper jobs fail intermittently with "Hyper Server did not call back on the callback connection."	DAP-42380
	Users are now able to export hyper formatted files to Tableau without any failures again after the associated plug-in has been updated.	Bug fixed.
