Hbase tutorial?

I tried to enter some test tables in hbase. The example was taken from
http://wiki.apache.org/lucene-hadoop/Hbase/HbaseShell but it fails no
matter which bloomfiler option I choose. Is there a better tutorial?

 

Hbase> CREATE TABLE webtable (

   --> contents MAX_VERSIONS=10 COMPRESSION=BLOCK,

   --> anchor MAX_LENGTH=256 BLOOMFILTER=COUNTING

   --> VECTOR_SIZE=1000000 NUM_HASH=4);

Syntax error : Type 'help;' for usage.

Message : Encountered "COUNTING" at line 1, column 104.

Hbase> 

Hope someone will answer this newbie question... 

 

\Peter

Try the following:

hql> create table webtable(
  --> contents MAX_VERSIONS=10 COMPRESSION=BLOCK,
  --> anchor MAX_LENGTH=256 BLOOMFILTER=COUNTING_BLOOMFILTER
  --> VECTOR_SIZE=10000 NUM_HASH=4);

* BLOOMFILTER=NONE|BLOOMFILTER|COUNTING_BLOOMFILTER|RETOUCHED_BLOOMFILTER

Thanks,
Edward.
