hbase coprocessor multinode cluster

2017-05-15 Thread Rajeshkumar J
Hi, I am currently analyzing hbase coprocessor and I tried run RowCountEndPoint in single node cluster it is working fine. But whn I try to run in multi node cluster it is not throwing error but it hangs in the sense it is not running continuously. I have loaded coprocessor dynamically. Thanks

-user@hbase to bcc (I encourage folks interest to subscribe to dev@hbase) Personally, I'd rather see us concentrate on getting MOB out the door in 2.0. branch-1 is now over 2 years old; I'd want some rigorous proof that we're not setting our downstream users up for surprises by making major

Call function from a coprocessor which extends BaseRegionObserver from the client side

I have a *Coprocessor* which overrides *postPut* and I also want to call a custom function in this Coprocessor from the hbase client. In hbase 0.94 I would use "*public class MyCoprocessor extends BaseRegionObserver implements MyCoprocessorProtocol*" but *CoprocessorProtocol *no longer exists in

Hi, Thanks ted. we are using default split policy and our flush size is 64 MB. And the size is calculated based on the formula Math.min(getDesiredMaxFileSize(),initialSize * tableRegionsCount * tableRegionsCount * tableRegionsCount); If this size exceeds max region size (10 GB), then max

region size for a mapper

2017-05-15 Thread Rajeshkumar J
Hi, As we run mapreduce over hbase it will take each region as input for each mapper. I have given region max size as 10GB. If i have about 5 gb will it take 5 gb of data as input of mappers?? Thanks
