Select this check box if the data from the preceding component is in
XML format.

When this check box is selected, a Column
list appears allowing you to select a Document type column of the schema that holds
the data, and the Row tag field
disappears.

When this check box is selected, in the Advanced
settings view, only the check boxes Create directory if not exists, Don’t generate empty file, Trim
data, tStatCatcher
Statistics and the list Encoding are available.

Row tag

Specify the tag that will wrap data and structure per row.

Schema and Edit
Schema

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

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: You create and store the
schema locally for this component only. Related topic: see
Talend Studio

User Guide.

Repository: You have already created
the schema and stored it in the Repository. You can reuse it in various projects and
Job designs. Related topic: see
Talend Studio

User Guide.

If the output is big, you can split the output into several files,
each containing the specified number of rows.

Rows in each output file: Specify the
number of rows in each output file.

Specify one or more root tags to wrap the whole output file structure and data. The
default root tag is root.

Define the output format.

• Column: The columns retrieved
  from the input schema.

• As attribute: select check box
  for the column(s) you want to use as attribute(s) of the parent
  element in the XML output.

Use schema column name: By
default, this check box is selected for all columns so that the
column labels from the input schema are used as data wrapping tags.
If you want to use a different tag than from the input schema for
any column, clear this check box for that column and specify a tag
label between quotation marks in the Label field.

Use dynamic grouping

Select this check box if you want to dynamically group the output
columns. Click the plus button to add one ore more grouping criteria
in the Group by table.

Column: Select a column you want
to use as a wrapping element for the grouped output rows.

Attribute label: Enter an
attribute label for the group wrapping element, between quotation
marks.

Select this check box to define the number of rows to buffer before
the data is written into the target file and the buffer is
emptied.

Row Number: Specify the number of
rows to buffer.

Select this check box to change the separator used for numbers. By default, the thousands separator is a comma (,) and the decimal separator is a period (.).

Thousands separator: define
separators for thousands.

Decimal separator: define separators
for decimals.

Encoding

Select the encoding from the list or select Custom and define it manually. This field is compulsory for database
data handling.

Trim data

Select this check box to remove the spaces at the beginning and at the
end of the text, and merge multiple consecutive spaces into one within
the text.

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.

NB_LINE: the number of rows processed. This is an After
variable and it returns an integer.

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 further information about variables, see
Talend Studio

User Guide.

Usage rule

Use this component to write an XML file with data passed on from other
components using a Row link.

Property type

Either Built-In or Repository.

Built-In: No property data stored centrally.

Click this icon to open a database connection wizard and store the database connection
parameters you set in the component Basic settings
view.

For more information about setting up and storing database connection parameters, see


Talend Studio
User Guide.

Repository: Select the repository file where the
properties are stored.

The properties are stored centrally under the Hadoop
Cluster node of the Repository
tree.

The fields that come after are pre-filled in using the fetched
data.

For further information about the Hadoop
Cluster node, see the Getting Started Guide.

Row tag

Specify the tag that will wrap data and structure per row.

Folder

Browse to, or enter the path pointing to the data to be used in the file system.

This path must point to a folder rather than a file, because a

Talend
Map/Reduce Job need to write in its
target folder not only the final result but also multiple part- files generated in performing
Map/Reduce computations.

Note that you need
to ensure you have properly configured the connection to the Hadoop
distribution to be used in the Hadoop
configuration tab in the Run view.

Action

Select an operation for writing data:

Create: Creates a file and write data
in it.

Overwrite: Overwrites the file
existing in the directory specified in the Folder field.

Specify one or more root tags to wrap the whole output file structure and data. The
default root tag is root.

Define the output format.

• Column: The columns retrieved
  from the input schema.

Usage rule

In a
Talend
Map/Reduce Job, it is used as an end component and requires
a transformation component as input link. The other components used along with it must be
Map/Reduce components, too. They generate native Map/Reduce code that can be executed
directly in Hadoop.

Once a Map/Reduce Job is opened in the workspace, tFileOutputXML as well as the MapReduce
family appears in the Palette of the
Studio.

Note that in this documentation, unless otherwise
explicitly stated, a scenario presents only Standard Jobs,
that is to say traditional
Talend
data integration Jobs, and non Map/Reduce Jobs.

Hadoop Connection

You need to use the Hadoop Configuration tab in the
Run view to define the connection to a given Hadoop
distribution for the whole Job.

This connection is effective on a per-Job basis.

Define a storage configuration
component

Select the configuration component to be used to provide the configuration
information for the connection to the target file system such as HDFS.

If you leave this check box clear, the target file system is the local
system.

The configuration component to be used must be present in the same Job. For
example, if you have dropped a tHDFSConfiguration component in the Job, you can select it to write
the result in a given HDFS system.

Property type

Either Built-In or Repository.

Built-In: No property data stored centrally.

Click this icon to open a database connection wizard and store the database connection
parameters you set in the component Basic settings
