I worked for a place that used HBase heavily. They migrated from AWS to GCP ~just for BigTable since the data model is essentially the same. They're a Java shop, and the drivers are actually the same. The workload of managing HBase and HDFS was high, and it was unreliable enough that they always had a failover cluster set up. Interestingly, the migration surfaced degenerate cells/tables that might have been partially to blame for reliability issues. Even 5 years ago, HBase was slowly dying, and at the end of the day, they didn't want the company's core competency to be HBase management.
