Question

我有Debian 6.03和最好的朋友hbase和hadoop的问题一步一步，我想要工作配置hbase（第一步独立）和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

但是，在hbase lib /文件夹中解压缩hadoop core v 1.0之后 - 我得到了：

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.

为什么在替换hadoop-core * .jar之后我需要独立的zookeeper？如何解决？

Answer 1

您是否配置了hbase-env.sh来管理Zookeeper本身？您是否在hbase-site.xml中配置了zookeeper仲裁？

Answer 2

我遇到了同样的问题，并通过配置yarn和map-reduce解决了这个问题。试试这个post。

在hbase / lib /中替换hadoop * .jar后，hbase 0.90.5无效
