The data flow to be processed must be added to
the flow in order for this component to fetch these data via the corresponding
representative variable.

This variable could be already pre-defined in
your Studio or provided by the context or the components you are using along
with this component; otherwise, you could define it manually and use it
according to the design of your Job, for example, using tJava or tJavaFlex.

In order to avoid the inconvenience of writing
manually, you could select the variable of interest from the auto-completion
list (Ctrl+Space) to fill
the current field on condition that this variable has been properly
defined.

stream, see Reading data from a remote file in streaming mode.

Schema and Edit Schema

A schema is a row description, it defines the
number of fields to be processed and passed on to the next component. The
schema is either Built-in or stored remotely in the Repository.

This
component offers the advantage of the dynamic schema feature. This allows you to
retrieve unknown columns from source files or to copy batches of columns from a source
without mapping each column individually. For further information about dynamic schemas,
see
Talend Studio

User Guide.

This
dynamic schema feature is designed for the purpose of retrieving unknown columns of a
table and is recommended to be used for this purpose only; it is not recommended for the
use of creating tables.

Click Edit
schema to make changes to the schema. If the current schema is of the Repository type, three options are available:

• View schema: choose this
  option to view the schema only.

• Change to built-in property:
  choose this option to change the schema to Built-in for local changes.

• Update repository connection:
  choose this option to change the schema stored in the repository and decide whether
  to propagate the changes to all the Jobs upon completion. If you just want to
  propagate the changes to the current Job, you can select No upon completion and choose this schema metadata
  again in the Repository Content
  window.

Built-in: The schema
will be created and stored locally for this component only. Related topic: see

Talend Studio
User Guide.

Repository: The schema
already exists and is stored in the Repository, hence can be reused in various
projects and Job designs. Related topic: see
Talend Studio
User Guide.

Global Variables

NB_LINE: the number of rows read by an input component or
transferred to an output component. This is an After variable and it returns an
integer.

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.

with data passed on from other components using a Row link.

Dynamic settings

Click the [+] button to add a row in the
table and fill the Code field with a context variable
to choose your HDFS connection dynamically from multiple connections planned in your
Job. This feature is useful when you need to access files in different HDFS systems or
different distributions, especially when you are working in an environment where you
cannot change your Job settings, for example, when your Job has to be deployed and
executed independent of
Talend Studio
.

The Dynamic settings table is
available only when the Use an existing
connection check box is selected in the Basic settings view. Once a dynamic parameter is
defined, the Component List box in the
Basic settings view becomes unusable.

For examples on using dynamic parameters, see Reading data from databases through context-based dynamic connections and Reading data from different MySQL databases using dynamically loaded connection parameters. For more information on Dynamic
settings and context variables, see Talend Studio
User Guide.
