Question:
FIWARE Cygnus can't persist in HDFSink

Description:
I want to persist information in Hadoop through Cygnus.
I'm testing the services, but in Cygnus log I receive this:

msg=org.apache.http.client.protocol.ResponseProcessCookies[129] : Invalid cookie header: "Set-Cookie: hadoop.auth="u=hduser&p=hduser&t=simple&e=1535600601906&s=PBVO9ijLyamz6JCcTEohe76tgl0="; Path=/; Expires=jue, 30-ago-2018 03:43:21 GMT; HttpOnly". Unable to parse expires attribute: jue, 30-ago-2018 03:43:21 GMT

[NGSIRestHandler] Bad HTTP notification (GET method not supported)
time=2018-08-29T17:53:25.008Z | lvl=WARN | corr=50e71d08-183d-4181-835a-09c5935adec4 | trans=50e71d08-183d-4181-835a-09c5935adec4 | srv=user_activity | subsrv=/user_activity | comp=cygnus-ngsi | op=doPost | msg=org.apache.flume.source.http.HTTPSource$FlumeHTTPServlet[192] : Deserializer threw unexpected exception.
org.apache.http.MethodNotSupportedException: GET method not supported

But in the console, I receive that everything is ok.

My notification.sh is like that:

!/bin/sh
URL=$1

if [ "$2" != "" ]
then
SERVICE=$2
else
SERVICE=default
fi

if [ "$3" != "" ]
then
SERVICE_PATH=$3
else
SERVICE_PATH=/
fi

curl $URL v -s -S --header 'Content-Type: application/json; charset=utf-8' --header 'Accept: application/json' --header 'User-Agent: orion/0.10.0' --header "Fiware-Service: $SERVICE" --header "Fiware-ServicePath: $SERVICE_PATH" -d @ <<EOF

"contextElement": {
"attributes": [

],
"type": "Room",
"isPattern": "false",
"id": "Room1"
},
"statusCode":

}]
}
EOF

The NGSI is not supposed to be intended to receive HTTP notifications as it is a REST API?

Can anyone help me? It's my first time using this kind of services and I am absolutely lost.

For more information, I am using Cygnus version 1.6.0.

Thank you.
