Hi all,

I installed Hadoop 0.20.2 and installed hive 0.5.0.

I followed all the instructions on Hive's getting started page for setting
up environment variables like HADOOP_HOME

When I run from command prompt in the hive installation folder as "bin/hive"
it gives me following exception

Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/hadoop/hive/conf/HiveConf
        at java.lang.Class.forName0(Native Method)
        at java.lang.Class.forName(Class.java:247)
        at org.apache.hadoop.util.RunJar.main(RunJar.java:149)
Caused by: java.lang.ClassNotFoundException:

        at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320)
        ... 3 more

Please note that my Hadoop installation is working fine.

What could be the cause of this? Anybody has any idea?

Thanks

Make sure hive-exec-0.7.0.jar is under lib/ dir.

Found: HiveConf
Class: org.apache.hadoop.hive.conf.HiveConf
Package: org.apache.hadoop.hive.conf
Library Name: hive-exec-0.7.0.jar

You need to run hive_root/build/dist/bin/hive, not hive_root/bin/hive.

We really need to hide <trunk>/bin/hive somewhere that people can not
find it so easily.

This should be documented in README.txt

It actually is.

Downloading and building
------------------------

- svn co http://svn.apache.org/repos/asf/hadoop/hive/trunk hive_trunk
- cd hive_trunk
- hive_trunk> ant package -Dtarget.dir=<install-dir> -Dhadoop.version=0.17.2.1

If you do not specify a value for target.dir it will use the default
value build/dist. Then you can run the unit tests if you want to make
sure it is correctly built:

...

Running Hive
------------

Hive uses hadoop that means:
- you must have hadoop in your path OR
- export HADOOP=<hadoop-install-dir>/bin/hadoop

To use hive command line interface (cli) from the shell:
$ cd <install-dir>
$ bin/hive

but for whatever reason people seem to been drawn to the bin/hive
right off the trunk. I think if we camouflaged that directory somehow
we might help stop people from wandering onto it.

Before mucking with the code, it should be worth a try to clarify the wiki first. It's easy to miss the point that <install-dir> is build/dist for most people; I guess people tend to mistake <install-dir> for <hive-root>. I would replace all references to <install-dir> by build/dist and just mention once that, for advanced users, you can change it to something else via blah blah config.
