Getting header information and saving in hbase

[Taimoor Aslam]

I used static interceptor and avro sink in client configuration to add custom 
information in headers , and in server configuration i used avro source and  
hbase sink to save the data in hbase table, but only the contents in body of 
the event saved in table, and  i also want to save incoming key value pairs in 
headers. How to ?
