Subject Re: hive.metastore.warehouse.dir - Should it point to a physical directory
Date Tue, 21 May 2013 18:04:08 GMT
Thanks Sanjay.
 
My environment is  like this.
 
$ echo $HADOOP_HOME
/software/home/hadoop/hadoop/hadoop-1.1.2
 
$ echo $HIVE_HOME
/software/home/hadoop/hive/hive-0.9.0

$ id
uid=50052(hadoop) gid=600(apps) groups=600(apps)

 
So can i do like this:
 
$pwd
/software/home/hadoop/hive/hive-0.9.0
 
$mkdir warehouse
 
$cd /software/home/hadoop/hive/hive-0.9.0/warehouse
 
$ in hive-site.xml<property>
  <name>hive.metastore.warehouse.dir</name>
  <value/software/home/hadoop/hive/hive-0.9.0/warehouse</value>
  <description>location of default database for the warehouse</description> 
</property>
 
Where should I create the HDFS directory ?

Subject: Re: hive.metastore.warehouse.dir - Should it point to a physical directory


Ok.I got it. 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

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.
