Hi Raj http://www.cloudera.com/content/cloudera-content/cloudera-docs/CDH4/latest/CDH4-Quick-Start/cdh4qs_topic_3.html
Installing CDH4 on a Single Linux Node in Pseudo-distributed Mode On the left panel of the page u will find info on Hive installation etc. I suggest CHD4 distribution only because it helps u to get started quickly…as developers I love to install from individual tar balls but sometimes there is little time to learn and execute There are some great notes here sanjay From: bharath vissapragada <bharathvissapragada1...@gmail.com<mailto:bharathvissapragada1...@gmail.com>> Date: Tuesday, May 21, 2013 11:12 AM To: "user@hive.apache.org<mailto:user@hive.apache.org>" <user@hive.apache.org<mailto:user@hive.apache.org>>, Raj Hadoop <hadoop...@yahoo.com<mailto:hadoop...@yahoo.com>> Cc: Sanjay Subramanian <sanjay.subraman...@wizecommerce.com<mailto:sanjay.subraman...@wizecommerce.com>>, User <u...@hadoop.apache.org<mailto:u...@hadoop.apache.org>> Subject: Re: hive.metastore.warehouse.dir - Should it point to a physical directory Yes !

Also there's a typo in your hive.xml: <value/software/home/hadoop/hive/hive-0.9.0/warehouse</value> Should be <value>/correct/path/in/hdfs/to/your/warehouse/directory</value> On Tue, May 21, 2013 at 1:04 PM, Raj Hadoop <hadoop...@yahoo.com<mailto:hadoop...@yahoo.com>> wrote: Thanks Sanjay.

My questions - 1) Should a local physical directory be created before using this property? I created a directory in HDFS during Hive installation /user/hive/warehouse My hive-site.xml has the following property defined <property> <name>hive.metastore.warehouse.dir</name> <value>/user/hive/warehouse</value> <description>location of default database for the warehouse</description> </property> 2) Should a HDFS file directory be created from Hadoop before using this property? hdfs dfs -mkdir /user/hive/warehouse Change the owner:group to hive:hive From: Dean Wampler <deanwamp...@gmail.com<mailto:deanwamp...@gmail.com>> To: user@hive.apache.org<mailto:user@hive.apache.org>; Raj Hadoop <hadoop...@yahoo.com<mailto:hadoop...@yahoo.com>> Cc: User <u...@hadoop.apache.org<mailto:u...@hadoop.apache.org>> Sent: Tuesday, May 21, 2013 1:44 PM Subject: Re: hive.metastore.warehouse.dir - Should it point to a physical directory The name is misleading; this is the directory within HDFS where Hive stores the data, by default. (External tables can go elsewhere). It doesn't really have anything to do with the metastore. dean On Tue, May 21, 2013 at 12:42 PM, Raj Hadoop <hadoop...@yahoo.com<mailto:hadoop...@yahoo.com>> wrote: Can some one help me on this ?

I ahve a question on the property hive.metastore.warehouse.dir. Should this point to a physical directory. I am guessing it is a logical directory under Hadoop fs.default.name<http://fs.default.name/>. Please advise whether I need to create any directory for the variable hive.metastore.warehouse.dir Thanks, Raj -- Dean Wampler, Ph.D. @deanwampler http://polyglotprogramming.com/ CONFIDENTIALITY NOTICE ====================== This email message and any attachments are for the exclusive use of the intended recipient(s) and may contain confidential and privileged information.
