Extended attributes -XATTR (-XATTR)

Use the -XATTR name=value[,name=value]* command to specify extended input and output attributes.

When used on the output, the adapter sets the specified extended attributes on the target file. If any of the attributes are already defined on the target file, they are overwritten with the specified new value.

When used on the input, it is only applicable in the Launcher when it is set on the input card on which source event watch is defined. In this case, the adapter inspects the watch file before it is reported as an event. This is to ensure that it has the specified extended attributes set to the specified values. Only those files that meet this criteria are reported.

For more information about extended attributes in HDFS see the HDFS documentation.
