Issue with Reciever REST Adapter PI 7.31 (SP15)

Hello

Below is the scenario :

Am trying to send data using REST adapter , but somehow the URL is getting truncated and not reaching the destination.

Any inputs will be really helpful.

The URL we send from PI is :

http://xxx.xx.x.xx:xxxxx/webhdfs/v1/user/hdfs/OB/PISourceFiles/Test/SAP/salesdata?op=CREATE&user.name=xxx.xx&permission=777

What we see in the network traffic is :

http://xxx.xx.x.xx:xxxxx/webhdfs/v1/user/hdfs/OB/PISourceFiles/Test/SAP/salesdata

Anything after '?' is getting truncated , not sure why.

Please advise and thank you in advance
