The default value of maxPostSize is 2M. This error occurs when transferring larger amounts of data.



  1. Open MDM\apache-tomcat\conf\server.xml for editing.
  2. Add maxPostSize="8000000" as shown below to set maxPostSize to 8 MB (adjust this value based on your needs).
  3. <Connector port="8180" protocol="HTTP/1.1" 
     redirectPort="8543" maxPostSize="8000000" />

  6. Open the Job in Studio > Run tab > Advanced settings > JVM, then increase the following parameters' values as shown (adjust the values based on your needs):
