Created November 15, 2018 14:32 — forked from ChristopherDavenport/HbaseClassloader.scala
HBase Class Loading Trick
/**
* Hacky Workaround for Getting the Current Context Classloader
* Executing Some arbitrary Sync with the Hbase Classloader
* Then reseting that thread to how it was previously.
*
* The moments I believe this is neccessary is when connections or
* configurations are being created to HBase. At these times it
* needs to have the hbase-default.xml which it will be lacking
* otherwise.

//Lmabda function1
//API1 : takes feature names as user input and returns all sub processses running status in response.
def lambda_handler(event, context):
config = load config from env variable.
take service names from user input(event)
extract corresponding micro services names mapped to feature name.
now we hit all machines where these micro services are running aggregate the status and return.
