I know that this is one of the topic that's asked much. Still after I digged into all of the topics I could find (most of them talking about CLASSPATH), I cant solve mine.
Examples of the topics I found and tried:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/HBaseConfiguration
java.lang.NoClassDefFoundError with HBase Scan
I'm using Hadoop 2.5.1 with HBase 0.98.11 on Ubuntu 14.04
I set up pseudo-distributed mode and running hadoop with hbase successfully. After I want to set up the full-distributed mode, jobs fail with NoClassDefFound error. I tried adding "export HADOOP_CLASSPATH=/usr/local/hbase-0.98.11-hadoop2/bin/hbase classpath" into hadoop-env (also yarn-env), still dont work.
One notice I found is if I comment the
<property>
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>
I can run the jobs SUCCESSFULLY. BUT it seems that I run it on single not multi node.
Here are some of the configs:
mapred-site
<property>
<name>mapred.job.tracker</name>
<value>hadoop1:54311</value>
<description>The host and port that the MapReduce job tracker runs
at. If "local", then jobs are run in-process as a single map
and reduce task.
</description>
</property>
<property>
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>`
hdfs-site
<property>
<name>dfs.replication</name>
<value>2</value>
<description>Default block replication.
The actual number of replications can be specified when the file is created.
The default is used if replication is not specified in create time.

</description>
</property>
<property>
<name>yarn.nodemanager.aux-services.mapreduce_shuffle.class</name>
<value>org.apache.hadoop.mapred.ShuffleHandler</value>
</property>
In yarn-env and hadoop-env there is just as default except the HADOOP_CLASSPATH (which doesn't change things even if I add it or not..)
Here is the error trace:

Really thanks for every help sir.
With Yarn, you need to set "yarn.application.classpath" property with the classpath for your MapReduce job. "export HADOOP_CLASSPATH" would not work with Yarn.

When I run:
hive --service hiveserver2 --hiveconf hive.server2.thrift.port=10000 --hiveconf hive.root.logger=INFO,console
It shows
Starting HiveServer2
and nothing listens on port 10000 and 10001
The HiveServer2 service does not output error information, causing it hard to diagnostic the problem. You can try to start the metastore service provided by Hive, which listens on port 9083 and might give some information when your configuration is not properly set:
hive --service metastore # not detach from terminal to see logs
In my case, this service cannot be started, with error message:
MetaException(message:Hive Schema version 3.1.0 does not match metastore's schema
version 1.2.0 Metastoed or corrupt)
One of the direct solution to resolve this error is to ignore the version difference by setting the hive-site.xml if there is only one hive version in your machine (another solution is to modify the metastore_db version):
<property>
<name>hive.metastore.schema.verification</name>
<value>false</value>
</property>
After this problem is resolved, the HiveServer2 service can be running and listening on port 10000.
hive --service hiveserver2 > /dev/null 2>&1 &
If your HiveServer2 access metastore via Derby or MySQL JDBC driver, then the aforementioned metastore service is not needed for HiveServer2. However, if HiveServer2 access metastore via thrift protocol, as configed in conf/hive-site.xml like
<property>
<name>hive.metastore.uris</name>
<value>thrift://hadoop-master:9083</value>
<description>
Thrift URI for the remote metastore.
Used by metastore client to connect to remote metastore.
</description>
</property>
Then, the metastore service must be started at first.
I had a hard time to set up hive-3.1.2. I write this maybe it helps someone out. in order to diagnose the problem first try to launch metastore and hiveserver2 like this:
metastore:
hive --service metastore --hiveconf hive.root.logger=INFO,console
hiveserver2:
hive --service hiveserver2 --hiveconf hive.server2.thrift.port=10000 --hiveconf hive.root.logger=INFO,console
then carefully read the the exceptions were thrown.
my problem was user hive is not allowed to perform this api call
and to solve that I added the following property to hive-site.xml:
<property>
<name>hive.metastore.event.db.notification.api.auth</name>
<value>false</value>
<description>
Should metastore do authorization against database notification related APIs such as get_next_notification.
If set to true, then only the superusers in proxy settings have the permission
</description>
</property>
also I add my full hive-site.xml as a sample:
<configuration>
<property>
<name>datanucleus.schema.autoCreateTables</name>
<value>true</value>
</property>
<property>
<name>javax.jdo.option.ConnectionURL</name>

</property>
<property>

Thanks. There is typo. It should hive.metastore not as shown below.
**metastore**.metastore.event.db.notification.api.auth
false

Manually adding jar with:
hdfs dfs -copyFromLocal -f /my.jar hdfs:///user/hbase/lib/my.jar
For function creation using:
CREATE FUNCTION MY_FUN(BINARY[], VARCHAR) RETURNS BOOLEAN as 'com.myCompany.phoenix.MyCustomFunction' using jar 'hdfs://localhost:57000/user/hbase/lib/my.jar';
I ran into something similar when I upgraded to Phoenix 5.0 from 4.7. I got an exception stating that I now needed to place my UDF .jar into /apps/hbase/data/lib due to permission issues. In the old environment I was able to get away using the /apps/hbase/lib directory. Maybe this is happening to you as well but it's not alerting you to the new path change.
I am using VirualBox to run Ubuntu 14 VM on Windows laptop. I have configured Apache distribution HDFS and YARN for Single Node. When I run dfs and YARN then all required demons are running. When I don't configure YARN and run DFS only then I can execute MapReduce job successfully, But when I run YARN as well then job get stuck at ACCEPTED state, I tried many settings regarding changing memory settings of node but no luck.
Following link I followed to set single node

Here is Application Master screen of RM Web UI. What I can see AM container is not allocated, may be that is problem
If the job is not getting enough number of resources, it will be in ACCEPTED state. Whenever it gets resources it will change to RUNNING state.
In your case, open Resource Manager WebUI and check how much of resources are available to run jobs.
Iam trying to create a hbase cluster in 3 centos machines. Hadoop(v - 2.8.0) is up and running on top I configured HBase(v - 1.2.5).Hbase start up is fine it started HMaster and Region servers but still it shows the follwing error in region servers and in HMaster log it shows no region servers are checked in.

We have an application managed by yarn when we change yarn-site.xml those changes are not reflected , application is still running with old configuration. We are new to Yarn any help in this regard will be helpful
Note : we have already tried restarted yarn using stop-yarn.sh and start-yarn.sh also restared dfs using start-dfs.sh and stop-dfs.sh . We are using hadoop 2.7.3
this is what yarn looks with only max memory configured to 16GB as shown in the picture but actual configuration is 22GB as per yarn-site.xml
