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. |
|
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
