what ZooKeeper is used for?
Hi there,
In Bigtable paper, it describes what Chubby is used for exactly :
.Ensure there is at most 1 active master at any time
.Store the bootstrap location
.Discover tablet servers and finalize tabler server death
.Store the schema information
.Store access control lists (not sure what it is)
In HBase0.20, what ZK is used for?
Thank you
Fleming
