creating flume agent in hortonworks sandbox vm for streaming weather data into HDFS

I am configuring flume to stream weather data, i have written flume agent as given below,

WeatherAgent.sources= Weather

WeatherAgent.sinks = hdfs-write

WeatherAgent.channels= memory-channel

WeatherAgent.sources.Weather.type = weather

WeatherAgent.sources.Weather.bind = api.openweathermap.org/data/2.5/forecast/city?id=524901&APPID=*********

WeatherAgent.sources.Weather.port = 11111

WeatherAgent.sinks.hdfs-write.type = hdfs

WeatherAgent.sinks.hdfs-write.hdfs.path = hdfs://localhost:8020/user/hadoop/flume

WeatherAgent.sinks.hdfs-write.rollInterval = 30

WeatherAgent.sinks.hdfs-write.hdfs.writeFormat=Text

WeatherAgent.sinks.hdfs-write.hdfs.fileType=DataStream

WeatherAgent.channels.memoryChannel.type = memory

WeatherAgent.channels.memoryChannel.capacity=10000

WeatherAgent.sources.Weather.channels=memoryChannel

WeatherAgent.sinks.hdfs-write.channel=memoryChannel

i am getting error as

weather agent does not contain any valid channels making it as invalid.

i am new to flume,i dont know which all parameters to be addded in agent config file,i even dont know written agent is correct or wrong,please help me to solve this. if any Help links are there to write custom or new agents please post.

thanks in advance

Solution

 it is type mismatching. In your configuration file you mentioned  

    WeatherAgent.channels= memory-channel

  but you are using  memoryChannel instead of memory-channel

    WeatherAgent.channels.memoryChannel.type = memory

    WeatherAgent.channels.memoryChannel.capacity=10000

    WeatherAgent.sources.Weather.channels=memoryChannel
