RE: what's the benifit of integrate hbase with hive? For low latency?

There are many potential benefits of using hive hbase handler. 1. The most obvious is ability to run SQL like queries on your data instead of using hbase client. 2. Ability to join data with other data sources like HDFS or S3. 3. Ability to move data from your Hive tables int

Hive Wiki: Editing Permissions

Hello, The Wiki has been one of the most important resources to me for learning Hive. There are a lot of broken links that make it hard to flip between topics. If I could gain editing permissions, I'd be happy to fix links and hopefully make this wiki a bit easier to learn from. Thanks

Re: what's the benifit of integrate hbase with hive? For low latency?

Hi Daniel, Integrating Hive with HBase does not solve the query latency problem, but it does allow you to run Hive queries against data which is being continuously updated -- something which is not possible with Hive alone. The following documents do a good job of discussing the use-cases that ar

what's the benifit of integrate hbase with hive? For low latency?

Hive document said hive is high latency, to query a table with about 100M might take 1 minute. And hbase is a high performance database, so does that mean after integrate hive and hbase, hive will get a better performance with lower latency?

Re: Hive or pig for sequential iterations like those using foreach

Thanks Amareshwari, the article gave me much valuable hints to decide my choice. But on curiosity, does hive support stage by stage iterative processing? If so how? Thank You Regards Bejoy K S -Original Message- From: Amareshwari Sri Ramadasu Date: Mon, 8 Aug 2011 17:14:21 To: user@h

You can have a look at typical use cases of Pig and Hive here http://developer.yahoo.com/blogs/hadoop/posts/2010/08/pig_and_hive_at_yahoo/ Thanks Amareshwari On 8/8/11 5:10 PM, "bejoy...@yahoo.com" wrote: Hi I've been successful using hive for a past few projects. Now for a particular use

Hive or pig for sequential iterations like those using foreach

Hi I've been successful using hive for a past few projects. Now for a particular use case I'm bit confused what to choose, Hive or Pig. My project involves a step by step sequential work flow. In every step I retrieve some values based on some query, use these values as input to new queries

Re: Error in hive - java.lang.RuntimeException: Could not load shims in class null

Ok. Sorted this out. Apparently in my maven repository there was a" append" jar present. I removed it manually, and rebuilt my code, and now everything works fine. Thanks, Mayuresh On Mon, Aug 8, 2011 at 3:01 PM, Mayuresh wrote: > Ok. Debugged this further. The version of hadoop that is determin

Re: Error in hive - java.lang.RuntimeException: Could not load shims in class null

Ok. Debugged this further. The version of hadoop that is determined is: "* 0.20-append-r1056497*" Obviously this doesn't match any of the versions given below and hence fails. Is there a way to overcome this? Am I doing something wrong? Thanks in advance. Regards, Mayuresh On Mon, Aug 8, 2011
