у меня Debian 6.03 и проблема с лучшими друзьями hbase и hadoop
шаг за шагом, я хочу рабочую конфигурацию hbase (автономно для первого шага) и 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
Но, после распаковки hadoop core v 1.0 в папку hbase lib / - я получил:
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.
Зачем мне нужен zookeeper в автономном режиме после замены hadoop-core * .jar?
как это исправить?
