Thank you Dima for the response.
Let me reiterate what I want to achieve in my case. I am using hbase to
persist my bigdata(Terabytes and petabytes) coming from various sources through
spark streaming and kafka. Spark streaming and kafka are running as separate
microservices inside different and excusive containers. These containers are
communicating with http service protocol. Currently I am using hbase setup on 4
VMs on a single host machine. I have a microservice inside a container to
connect to this hbase. This whole setup is functional and I am able to persist
data into as well as get data from hbase into spark streaming. My use case is
of real time ingestion into hbase as well as real time query from hbase.
Now I am planning to deploy hbase itself inside container. I want to
know what are the options for this. In how many possible ways I can achieve
this ? If I use volumes of container, will they be able to hold such amount of
data (TBs & PBs) ? How will I setup up hdfs inside volumes ? how can I use the
power of distributed file system there? Is this the best way ?
Thanks,
Udbhav

Udbhav,
Volumes are Docker's way of having folders or files from the host machine
bypass the union filesystem used within a Docker container. As such, if a
container with a volume is killed, the data from that volume should remain
there. That said, if whatever caused the container to die affects the
filesystem within the container, it would also affect the data on the host.
Running HBase in the manner you've described is not typical in anything
resembling a production environment, but if you explain more about your use
case, we could provide more advice. That said, how you'd handle data locality
and, in particular, multi-host deployments of HBase in this manner is more of a
concern for me than volume data corruption. What kind of scale do you need to
support? What kind of performance do you expect?
