The minimum processing unit of HBase in Fusioninsight HD system is Region. Where is the routing information between User Region and RegionSeiver stored?
I feel like I’ve seen a question similar to this before, and I think it was about the Master storing some routing info, but I can't recall the details.
I'm leaning towards the meta table as the answer. That's where HBase stores metadata about the regions and their locations, so it makes sense that the routing information would be stored there.
Okay, I think I've got this. The routing information is stored in ZooKeeper, which is responsible for coordinating the HBase cluster and keeping track of the location of regions.
Hmm, I'm a bit unsure about this one. The question is specifically asking about the routing information between the User Region and RegionServer, so I'll need to think carefully about where that information is stored.
This seems like a straightforward question about HBase architecture. I'll start by reviewing what I know about the role of ZooKeeper, HDFS, and the HBase Master in the system.
Clearly, the answer is D. The meta table is where all the routing and location information for the regions is stored. It's like the phone book of HBase!
