             Summary: Loosing HBase data when region server goes down
                 Key: HBASE-20600
                 URL: https://issues.apache.org/jira/browse/HBASE-20600
             Project: HBase
          Issue Type: Bug
            Reporter: Nandakishore


Hi Team,

I have a issue with HBase cluster. 

I have hosted an HBase cluster with Phoenix on EMR emr-5.8.0 and storage as S3. I have 1 master and 5 slaves 4.x large nodes. I’m losing the data while querying a table after a region server dies. Here are the steps I followed. 

1. Launched the cluster with dfs replication factory as 3.
2. Created the tables and loaded the data using Phoenix. 
3. Cross checked the data I loaded into tables and I see the data. 
4. Wantedly terminated a EC2 machine which is part of cluster, meaning killing region server.
5. I could see EMR resizing and bringing up the new node. 
6. When I query the table after the whole cluster is stable, which usually took 5-10 minutes, I see losing some data which is on dead RS. 

Could you please let me know what possibly could go wrong. Also please let me know if I have to set any properties.

I would be happy to provide more details if you need. 

Thanks,
Nandakishore.
