We have file in certain directory/ftp from 10MB to 100MB at interval of 1 min to hours. What would be the proper architecture to harvest data for real time consumption and batch analysis. I have though of following architecture: files --> flink --> Hbase (Real time query) files --> flink --> HDFS or files --> HDFS --> flink --> Hbase What is the most appropriate architecture for this purpose? What tools should I use? I want to use flink because I would like to get metric during transformation. ... View more

Easy way to detect duplicate value is: select component_name, service_name, host_id, cluster_id,count(*) from ambari.hostcomponentdesiredstate group by component_name, service_name, host_id, cluster_id order by count desc; select component_name, service_name, host_id, cluster_id,count(*) from ambari.hostcomponentstate group by component_name, service_name, host_id, cluster_id order by count desc; You will find that count of one of the table is different from other. Just delete that by id and you are good to go. ... View more
