Usual Errors encountered when using HBase

Error 1: Error on the hbase shell
Exception in thread "main" java.lang.NoClassDefFoundError: org/jruby/Main
Caused by: java.lang.ClassNotFoundException: org.jruby.Main
      at java.net.URLClassLoader$1.run(URLClassLoader.java:217)
      at java.security.AccessController.doPrivileged(Native Method)
      at java.net.URLClassLoader.findClass(URLClassLoader.java:205)
      at java.lang.ClassLoader.loadClass(ClassLoader.java:321)
      at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294)
      at java.lang.ClassLoader.loadClass(ClassLoader.java:266)
Could not find the main class: org.jruby.Main. Program will exit.

Solution: This is most likely a version incompatibility issue, which I had encountered when trying to run hbase-0.20.4 with hadoop 0.20.1
The same setup of Hadoop was working fine with hbase-0.20.1, hbase-0.20.2 and hbase-0.20.3. Hence try with some other version of either Hadoop or HBase.

Error 2: Error on the hbase shell
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/zookeeper/ZKServerTool
Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.hbase.zookeeper.ZKServerTool
      at java.net.URLClassLoader$1.run(URLClassLoader.java:217)
      at java.security.AccessController.doPrivileged(Native Method)

      at java.lang.ClassLoader.loadClass(ClassLoader.java:266)
Could not find the main class: org.apache.hadoop.hbase.zookeeper.ZKServerTool. Program will exit.
 
Solution: Same as that for Error 1 above

Error 3: Error in the master logs
ERROR org.apache.hadoop.hbase.master.HMaster: Cannot start master
Caused by: java.net.ConnectException: Call to hadoop-4252-nameserver/192.168.41.123:9000 failed on connection exception: java.net.ConnectException: Connection refused

Solution: When getting the above error, my /etc/hosts file on the HBase Master node was something like below:

127.0.0.1   hbase-master      localhost.localdomain   localhost
::1   hbase-master      localhost6.localdomain6 localhost6
192.168.41.123  hbase-master
192.168.41.123  localhost
192.168.41.123  localhost.localdomain
And to resolve the error, I edited it to be

192.168.41.123  hbase-master
192.168.41.123  localhost
192.168.41.123  localhost.localdomain

After which the above error went away.

  1. Greetings,
    I have installed Hadoop + HBase 6 node cluster with 1 master and 5 slaves/regionservers. However, mine setup is not working properly and I can not understnd why. I have installed Hadoop and I have all its's processes running. After I setup HBase and run /start-hbase.sh it says that all nodes have started but when I run "jps" I only have Hadoop processes running and nothing from HBase. After, when I try to use shell I get : "ERROR: org.apache.hadoop.hbase.MasterNotRunningException: Retried 7 times"
    Also, when I try to /stop-hbase.sh I get "localhost: no zookeeper to stop because kill -0 of pid 22876 failed with status 1".
    On logs I have: ERROR org.apache.hadoop.hbase.master.HMasterCommandLine: Failed to start master
    java.lang.RuntimeException: HMaster Aborted
    at org.apache.hadoop.hbase.master.HMasterCommandLine.startMaster(HMasterCommandLine.java:153)

    1. Hello,

      Clearly the HBase Master is not starting and hence all the errors.

      Could you check if the port on which HBase Master runs is not already occupied?

      Because with the given information, its not clear what's the issue which is aborting the master.

  6. Hi Jayati,
    Kudos for your blog, i keep following all your contents, its really helpful...i have solved many issues after finding a solution from your blog.

    I am facing the Hbase issue, Failed construction of Master: class, i have tried the solution which you have provided above, but still i get this.

    Hbase is not starting at the first run.. i am trying to install hbase from cloudera manager.
