Hello Ted,
Yes, I saw that mail when I googled. I'm pretty sure I didn't have the same
problem. I used the stable release tarball, which only has one bin dir, which I
ran the exe from.
Adding Classpath back onto HADOOP_CLASSPATH worked for me.
Was my solution misleading? I wouldn't want to confuse people, but it did work
once I added that back on..
Thanks!
Take care,
-stu

Please see Edward's reply to 'Exception in hive
startup' on Oct 13th.
Try running with <install-dir>/bin/hive

Hello,
I'm just starting with hive, and I ran into a newbie problem that didn't
have a solution via google. So I thought I'd record the solution for posterity
(and other hapless newbies) :)
I've been using hadoop/hbase for a while, and have configured hadoop-env.sh a
bit here and there (to work with hbase, etc). At some point, I dropped the
$CLASSPATH off the end of the standard line:
export
HADOOP_CLASSPATH=/home/stu/hbase/hbase-0.20.6.jar:/home/stu/hbase/hbase-0.20.6-test.jar:/home/stu/hbase/conf:/home/stu/hbase/lib/zookeeper-3.2.2.jar:$CLASSPATH
So it became:
# Extra Java CLASSPATH elements. Optional.
export
HADOOP_CLASSPATH=/home/stu/hbase/hbase-0.20.6.jar:/home/stu/hbase/hbase-0.20.6-test.jar:/home/stu/hbase/conf:/home/stu/hbase/lib/zookeeper-3.2.2.jar
(probably when I added the hbase stuff or something). My hadoop/hbase set up
runs fine, so I never noticed.
Well, if you do that, and you try to run the hive shell, you get the:
s...@ubuntu-update:~/hive-0.6.0/bin/ext$ /home/stu/hadoop-0.20.2/bin/hadoop jar

error, even if you've followed the wiki correctly and set HADOOP_HOME and
HIVE_HOME correctly. Note the command line above is a little strange, because I
was debugging through the $HIVE_HOME/bin/hive script... (So I printed out the
classpath it was forming, set it by hand, ran the instructions by hand, etc).
This is installing from the hive tar (stable). But that doesn't matter.
Anyways, hope the answer helps someone..
Best,
