Hello, I'm looking your answer 3 years later because I'm in a similar situation :). In my company (telco) we're planning using 2 hot clusters with dual ingest because our RTO is demanding and we're looking for mechanisms to monitor and keep in sync both clusters. We ingest data in real-time with kafka + spark streaming, loading to HDFS and consuming with Hive/Impala. I'm thinking about a first approach making simple counts with Hive/Impala tables on both clusters each hour/half hour and comparing. If something is missing in one of the clusters, we will have to "manually" re-ingest the missing data (or copy it with cloudera BDR from one cluster to the other) and re-process enriched data. I'm wondering if have you dealt with similar scenarios or suggestions you may have. Thanks in advance! ... View more
