Hi all,

I just upgraded from HBase 0.90.2 to 0.94 (running on hadoop 0.20.3).

It seems like the cluster is up and running.

I tried running an old MR job that writes into HBase, and after Map is
complete (map 100%) and before Reduce begins (reduce 0%) - I got the
following Exception:

12/05/29 12:32:02 INFO mapred.JobClient: Task Id :

I saw something about the dependencies in HBASE-5497 and 5460 - but I
understand that those were fixed in 0.94...

Any ideas ?

Thanks,
Amit.

Are you sure that 0.94 is compatible with Hadoop 0.20.3?

could anyone recommend a compatible Hadoop version for HBase 0.94 ?

Should I also upgrade zookeeper (3.3.2) ?

Thanks.

Yo have to check in the docs version, in the section 2.3 Hadoop of the
HBase book, which is the
compatible version:
http://hbase.apache.org/book/book.html#hadoop

You have protobuf on your CLASSPATH when the job runs?

St.Ack

I do.

I tried with protobuf-java-2.4.0a.jar that ships with HBase 0.94, and also
with the older version I had - protobuf-java-2.3.0.jar.

Both times I got the same error..

I'd suggest you keep on digging down this vein.  ClassNotFound is a
pretty basic complaint w/ usually, a pretty basic explaination.

St.Ack

How are you setting up your M/R jobs?
A while ago (0.92 I think) I added the necessary protobuf jars to the jar dependencies in HBase's TableMapReduceUtil.

Hi  Amit,  I meet this error on the client side when I upgrade 0.92.1 to
0.94.
I just put protobuf-java-2.4.9.a.jar into the classpath then the problem
sloved.

if you're sure you have protobuf on your CLASSPATH when the job runs,  have
you just try restart M/R or even Hadoop?
I met some strange classNotFound Exceptions when I run mapR before, just
restart, and everything may return well.

you mean protobuf-java-2.4.04.jar or there is a new version like you
wrote protobuf-java-2.4.9.a.jar ?

I'm sorry i made a mistack. my protobuf's version is 2.4.0.a.jar. I got it
from Hbase0.94's lib.

I got a way. just export the hadoop classpath like this: export
HADOOP_CLASSPATH=/home/chianyu/hbase-0.94.0/hbase-
0.94.0.jar:/home/chianyu/hadoop-1.0.3/hadoop-core-1.0.3.jar:/home/chianyu/hbase-
0.94.0/lib/zookeeper-3.4.3.jar:/home/chianyu/hbase-0.94.0/lib/protobuf-java-
2.4.0a.jar
that's all ok!
