Capturing HIVE CLI errors

Hi guys, I am trying to write a client code for HIVE CLI via ODBC connector. I want to add query validation code at my client side. I was wondering is there a way I can capture the Hive query syntax errors which I can use to validate at my client end. I don't want to write my own validation codes

Re: How to load csv data into HIVE

You can use hadoop streaming that would be much faster... Just run your cleaning shell script logic in map phase and it will be done in just few minutes. That will keep the data in HDFS. Regards, Praveenesh On Fri, Sep 7, 2012 at 8:37 PM, Sandeep Reddy P wrote: > Hi, > Thank you all for your he

adoop streaming or pig scripts can help you to do that. Probably someone in community can give better answer to the exact problem. I hope it would help. Regards, Praveenesh On Fri, Sep 7, 2012 at 8:13 AM, 曹坤 wrote: > Hi praveenesh kumar : > I am getting the same error today. > D

Starting hive thrift server as daemon process ?

Re: Problem in reduce phase(critical)

Logs are saying your reducer is not able to communicate with the mapper.. Its waiting for map-outputs. It could be internet problem or ssh problem. Check your machine 'hadoopdata3' -- Are you able to ping it from all other machines and ssh into it without password from your NN and JT? Thanks, Prav

New to hive

Guys, I have been using hadoop for 3,4 months. Tried Map Reduce, HBase, Pig. Now wanted to learn HIVE. I hope it must be as exciting as other hadoop tools. Can someone suggest me some good tutorials, apart from HIVE wiki, which I can utilize to understand and work on hive ? Thanks, Praveenesh
