I couldn't find the relationship between Slider and Regionservers. Do you have
a specific link?
What I'm looking for is something like this:
using the java native client:
- get a list of regions
- for each region, get the name of the region server
- somehow find a record belonging to that regio
Health check can be as simple as pinging - see
https://issues.apache.org/jira/browse/HBASE-17453
To get list of regions, see this post:

Hello,
I attempted HBase replication for the first time and am trying to
understand how it works.
I have three HBase clusters each with their own ZK ensemble, A, B, C. I
wanted to have complete acyclical replication between all 3 clusters, so I
added B as a peer of A, C as a peer of B, A as a pee
Hello,
I'm evaluating HBase as a cheaper replacement for NAS as a file storage
medium. To that end I have a cluster of 5 machines, 36TB HDD each; I'm
planning to initially store ~240 million files of size 1KB-100MB, total
size 30TB. Currently I'm storing each file under an individual column, and

Have you read:
http://hbase.apache.org/book.html#hbase_mob
In particular:
When using MOBs, ideally your objects will be between 100KB and 10MB
Cheers

Thank you Ted for your response.
I have read that part of HBase book. It never explained why objects over
10MB are no good, and did not suggest an alternative storage medium for
these.
I have also read this:

And yet I'm trying t
Hello,
Did you check the RegionServer logs, was there any exception ?

Hi Daniel,
I think it is because the memory burden in both clients and servers.
If we have a row with large size, we have to have a hfile block with a
large size which will heavy the burden of the block cache if the data block
would be cached. And in scanning, both region servers and clients will
