Hi,
I have installed the Hadoop/Hbase. Can you please clarify me the following questions 1) I am having my hmaster running. when I start my regional server on the other host. I am getting the following Exception. can you please let me know what I am missing and also how to debug this? == sudo /sbin/service hadoop-hbase-regionserver start starting regionserver, logging to /var/log/hbase/hbase-hbase-regionserver-host123.out Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/zookeeper/KeeperException at java.lang.Class.getDeclaredMethods0(Native Method) at java.lang.Class.privateGetDeclaredMethods(Class.java:2442) at java.lang.Class.getMethod0(Class.java:2685) at java.lang.Class.getMethod(Class.java:1620) at sun.launcher.LauncherHelper.getMainMethod(LauncherHelper.java:484) at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:476) Caused by: java.lang.ClassNotFoundException: org.apache.zookeeper.KeeperException at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) == 2) My Hadoop is up and running. But when I try to connect to the Hbase from my BRoswer, I keep getting "connecting" in the status Bar and no response. I tried: http://10.10.10.11:60010 when I checked Hmaster it is running on 10.10.10.11. but the GUI does not come 3) I have a Hadoop and Hbase installed in 5 hosts. if I want this to be given to 25 applications for accessing the DB, what are the configuration changes that I should be taken into consideration like: ( in some applications max handles , threads) similarly what all I should be taken into consideration. 4) when I try to connect to HBase shell it stops and does not proceed. = hbase(main):006:0* list TABLE 11/12/11 18:25:57 FATAL zookeeper.ZKConfig: The server in zoo.cfg cannot be set to localhost in a fully-distributed setup because it won't be reachable. See "Getting Started" for more information. = Thanks again in advance. -Adi
