Ok, I solved the problem copying the required jars in $HADOOP_HOME/lib folder.
Thanks,

Cheolsoo, doing so I obtain a ClassNotFoundException:
ERROR 2998: Unhandled internal error.
org/apache/hadoop/hbase/filter/WritableByteArrayComparable
That's a very strange thing since I'm sure that package is in the CLASSPATH.
Are you using Hadoop 1.0.0 or 1.0.1?

Hi Alberto,
Here is my local setup that works. Please change them accordingly to your
environment.
1) I started hbase-0.94 in standalone mode.
2) I downloaded hadoop-1.0.0.
3) I built "pig-withouthadoop.jar" from the source and ran the following
commands:
export HADOOP_HOME=/home/cheolsoo/worksp
Thanks Cheolsoo.
I've already seen that link. But it is not so much clear to me how Pig
makes use of HBase jars.
Even if I use Pig in MapReduce mode (real or pseudo-distributed) it
needs HBase on the client, right?
In my particular case I use Pig in a real distributed cluster (but I
tested it also
Hi Alberto,
Are you running in local mode using "pig.jar", or in mapreduce mode using
"pig-withouthadoop.jar"?
The error that you're seeing can happen when there is a version mismatch in
the HBase client and server. The pig.jar by default contains hbase-0.90, so
if you use pig.jar against hbase-0
Hi all,
I'm currently working with Pig 0.10.0. I'd like to load some data from
an HBase table, but I encountered some problems. When I try to load
the data it seems to work:
grunt> raw = LOAD 'hbase://table_test' USING
org.apache.pig.backend.hadoop.hbase.HBaseStorage('d:data1', '-loadKey
true -li
That was it! I don't think that I even had my HBase path on the
PIG_CLASSPATH, at all. I simply put HBase on the path and now it works.
Thank you,
Ryan

The classpath for Pig, correct?

Ryan,
This message is specific to Hbase 0.92.1 . Make sure HBase 0.90.1 jar is
not in the classpath before the 0.92.1 jar files

Hmm. The data in my tables is not important. So, I dropped the table and
recreated it. This doesn't seem to have resolved the issue, though.
Is there perhaps a Pig query I can run that would use a built in HBase table,
like that .META. table, and see if it works? I don't know if that'd help or
Actually on second glance, this seems like an issue not with the HBase
config, but with the server:port info inside your .META. table. Have you
tried LOADing from a different table besides "events"? From the HBase
shell, you can use the following command to extract server hostnames for
each of yo
I was thinking that maybe it was because I did not have HBase config path
on PIG_CLASSPATH, so I added it. This did not help, though.

Norbert,
I have confirmed that this is indeed an issue connecting to HBase. I tried
just running a Pig script that did not use HBaseStorage, and it works. Here
is my hbase-site.xml config file, as well as my query that I'm running:

Also, for ease of reference, her
You're encountering problems connecting to HBase (presumably your Pig
script uses HBaseStorage). How does your hbase/conf/hbase-site.xml look?

Hello,
I'm new to these lists. I'm trying to get Pig working, for my first time. I
have setup Hadoop and HBase (on HDFS) using the psuedo-distributed setup,
all on one machine. I am able to run MapReduce jobs, using the example.jar
file included with the Hadoop release.
