question about multi-transaction queries

Hello. We plan to run a set of queries on tables with multiple columns. What is the most efficient method to say, insert 1000 rows, and/or read 1000 rows. We are considering just using REST. But what about jython? Will it be faster? Another way to have our apps talk to nginx and some sort of a

Result different between remote Client and HBase Shell

Hi all, I've run across an interesting problem. I have imported a few thousand rows into HBase and when I do a 'scan' from the shell tool I get back a different amount of rows than if I do the same query with a remote Java Client. scan tool command... hbase(main):030:0> scan 'TrafficLog', {ST

thirft mutateRows transaction

I was looking through the thirft API again and noticed that it said if a transaction - comprised of updates to one or more rows - throws an exception then the whole transaction is aborted. Does this mean that it is atomic and none of the updates will be executed or could some subset of them be e

Re: RegionServer crashed with ZK session expired

It seems your RS was under relatively high read and write load as you can tell by both LRU evictions and that the global memstore size limit was reached. With so much heap used and multiple clients coming in, it could put a lot of pressure on your JVM's memory. That, and the fact that you are on E

Re: Determine in which row a column exists

Yes, I say that. To my understanding you wanted to avoid scan, so i thought you might denormalize a bit more with another table. If you want to keep just one of the two, your usage pattern will help you with your choice. If you'll stick for a scan on your actual table, you'll have a big number of

Re: Determine in which row a column exists

Claudio, You say that I can flip the data, right? If I understand your suggestion correctly, then getting products that a cluster includes will be the problem. Actually, in google's BigTable paper, their example table is similar, also their example code to retrieve data: Scanner scanner(T); ScanSt

Re: RegionServer crashed with ZK session expired

Hi J-D, Thank you for response. Right, I see in logs the pause. I see it in both ZK log and regionserver (I pasted respective parts of logs with previous message). Just not sure about the cause of the pause. Anyways, I restarted things with GC being logged this time. Will inspect the issue if I f

Hi, We have the output of a clustering algorithm in an hbase table which has the following structure: {NAME => 'clusters', FAMILIES => [{NAME => 'products', COMPRESS true ION => 'NONE', VERSIONS => '3', TTL => '2147483647', BLOCKSIZE => '655 36', IN_MEMORY => 'false', BLOCKCACHE => 'true'}]} r

RE: Hive HBase integration scan failing

Hey, Need some more info. Can you paste logs from the MR tasks that fail? What's going on in the cluster while the MR job is running (cpu, io-wait, memory, etc)? And what is the setup of your cluster... how many nodes, specs of nodes (cores, memory, RS heap), and then how many concurrent map
