Configuring Sandboxing for the File/Hadoop Event XML Input and Output AdapterLocate this document in the navigation structure

To avoid overwriting files, configure the File/Hadoop Event XML Input and Output adapter to only read and write files in the sandbox base directory. If the adapter is running in unmanaged mode, update the controller.xml file to change the directory in which the File/Hadoop Event XML Input and Output adapter reads and writes files to the adapter sandbox base directory.

Procedure

  1. In the controller.xml file, configure the following parameters:
    • For AdapterSandboxBase, set the path of the sandbox base directory.
    • For EnableSandboxing, set the value to true.

      For example,

    <Controller>
  <ControlPort>
     <MinPort>19082</MinPort>
     <MaxPort></MaxPort>
  </ControlPort>
  <Statistics_Update_Interval>5000</Statistics_Update_Interval>
  <MonitorInterval>3000</MonitorInterval>
  <AdapterSandboxBase><sanbox_base_directory_file_path></AdapterSandboxBase>
  <EnableSandboxing>true</EnableSandboxing>
</Controller>
  2. Set the environment variable STREAMING_SANDBOX_ENABLE to TRUE.
    For the File/Hadoop Event XML Input adapter, the file path configured in the File Input Transporter will redirect all file access to the subfolder of the directory configured in AdapterSandboxBase. For the File/Hadoop Event XML Output adapter, the file path configured in the File Output Transporter will redirect all file access to the subfolder of the directory configured in AdapterSandboxBase.
    Note For both the File/Hadoop Event XML Input and Output adapter, the sandbox base directory does not redicrect files to and from a Hadoop Distributed File System (HDFS).
