Subject Hbase 0.90.5 and Hadoop 1.0.0 beta working?
Date Sat, 21 Jan 2012 06:25:52 GMT
Hi, i have Debian 6.03 and problem with best friends hbase and hadoop
step by step, I want working configuration hbase (standalone for the 
first step) and hadoop :

wget http://www.sai.msu.su/apache//hbase/hbase-0.90.5/hbase-0.90.5.tar.gz
tar xzfv hbase-0.90.5.tar.gz
sudo mv hbase-0.90.5 /usr/local/
sudo ln -s hbase-0.90.5/ hbase
sudo chown -R hduser:hadoop hbase*
lrwxrwxrwx  1 hduser hadoop   13 Янв 21 10:11 hbase -> hbase-0.90.5/
drwxr-xr-x  8 hduser hadoop 4096 Янв 21 10:11 hbase-0.90.5
dan@master:/usr/local/hbase$ su hduser
hduser@master:/usr/local/hbase$ bin/start-hbase.sh
starting master, logging to 
/usr/local/hbase/bin/../logs/hbase-hduser-master-master.out
hduser@master:/usr/local/hbase$ bin/hbase shell
HBase Shell; enter 'help<RETURN>' for list of supported commands.
Type "exit<RETURN>" to leave the HBase Shell
Version 0.90.5, r1212209, Fri Dec  9 05:40:36 UTC 2011

hbase(main):001:0> list
TABLE
0 row(s) in 0.8560 seconds

But, after unpack hadoop core v 1.0 in hbase lib/ folder - I got:

hduser@master:/usr/local/hbase$ bin/stop-hbase.sh
hduser@master:/usr/local/hbase$ cp ../hadoop/hadoop-core-1.0.0.jar lib/
hduser@master:/usr/local/hbase$ rm lib/hadoop-core-0.20-append-r1056497.jar
hduser@master:/usr/local/hbase$ bin/start-hbase.sh
starting master, logging to 
/usr/local/hbase/bin/../logs/hbase-hduser-master-master.out

hduser@master:/usr/local/hbase$ bin/hbase shell
HBase Shell; enter 'help<RETURN>' for list of supported commands.
Type "exit<RETURN>" to leave the HBase Shell
Version 0.90.5, r1212209, Fri Dec  9 05:40:36 UTC 2011

hbase(main):001:0> list
TABLE

ERROR: org.apache.hadoop.hbase.ZooKeeperConnectionException: HBase is 
able to connect to ZooKeeper but the connection closes immediately. This 
could be a sign that the server has too many connections (30 is the 
default). Consider inspecting your ZK server logs for that error and 
then make sure you are reusing HBaseConfiguration as often as you can. 
See HTable's javadoc for more information.

Why I need zookeeper on standalone after replace hadoop-core*.jar?
how to fix it?
