Thanks Deepak. 
Does this mean Streaming from HBase is not possible using current Streaming API?
Also request you to shred some light on HBase checkpointing. I referred the 
below URL to implement checkpointing however in the example I see count is 
passed in the SourceFunction ( SourceFunction<Long>) Is it possible to 
checkpoint based on the data we read from HBase

 I would suggest another approach here.1.Write a job that reads from hbase , 
checkpoints and pushes the data to broker such as Kafka.2.Flink streaming job 
would be the second job to read for kafka and process data.
With the separation of the concern as above , maintaining it would be simpler.
ThanksDeepak

 Hi Team,
I recently encountered one usecase in my project as described below:
My data source is HBaseWe receive huge volume of data at very high speed to 
HBase tables from source system.Need to read from HBase, perform computation 
and insert to postgreSQL.
I would like few inputs on the below points:   
   - Using Flink streaming API,  is continuous streaming possible from HBase 
Database? As I tried using RichSourceFunction ,StreamExecutionEnvironment  and 
was able to read data but Job stops once all data is read from HBase. My 
requirement is Job should be continuously executing and read data as and when 
data arrives to HBase table.
   - If continuous streaming from HBase is supported, How can Checkpointing be 
done on HBase so that Job can be restarted from the pointed where Job aborted. 
I tried googling but no luck. Request to help with any simple example or 
approach. 
   - If continuous streaming from HBase is not supported then what should be 
alternative approach - Batch Job?(Our requirement is to process the realtime 
data from HBase and not to launch multiple ETL Job)

Happy Christmas to all  :)

Regards,Sunitha.
