Basic settings

Property Type

  • Repository: The connection details stored centrally in Repository > Metadata will be reused by this component.

    You need to click the [...] button next to it and in the pop-up Repository Content dialog box, select the connection details to be reused, and all related connection properties will be automatically filled in.

Hive principal uses the value of hive.metastore.kerberos.principal. This is the service principal of the Hive metastore.
Use SSL encryption Select this check box to enable the SSL or TLS encrypted connection.
Then in the fields that are displayed, provide the authentication information:
  • In the Trust store path field, enter the path, or browse to the TrustStore file to be used. By default, the supported TrustStore types are JKS and PKCS 12.

Global Variables

Global Variables

ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl+Space to access the variable list and choose the variable to use from it.

For more information about variables, see Using contexts and variables.
