带有YARN的HBase引发错误

Question

I'm using Hadoop 2.5.1 with HBase 0.98.11 on Ubuntu 14.04

I could run it in Pseudo-distributed mode. Now that I want to run on distributed mode. I follow the instruction from sites and end up having an error in RUNTIME called "Error: org/apache/hadoop/hbase/HBaseConfiguration" (while there is no error when I compile the code).

After trying things, I found that if I comment the mapreduce.framework.name in mapred-site.xml and also stuffs in yarn-site, I could be able to run the hadoop successfully.

But I think it's the single-node running (I have no idea, just guessing by comparing the running time to what I ran in Pseudo and there is no MR in slave's node jps when running the job on master).

Here are some of my conf:

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.

Thank you so much for every help

UPDATE: I try making some changes to the yarn-site by adding yarn.applicaton.classpath like this

The error changed to EXIT CODE.

UPDATE2: In syslog of the application logs it says

Any suggestions pls

Answer 1

I guess that you didn't set up your hadoop cluster correctly please follow these steps :

Hadoop Configuration:

step 1 : edit hadoop-env.sh as following:

# The java implementation to use.  Required.
export JAVA_HOME=/usr/lib/jvm/java-6-sun

step 2 : Now create a directory and set the required ownerships and permissions

$ sudo mkdir -p /app/hadoop/tmp
$ sudo chown hduser:hadoop /app/hadoop/tmp
# ...and if you want to tighten up security, chmod from 755 to 750...
$ sudo chmod 750 /app/hadoop/tmp

step 3 : edit core-site.xml

<property>
  <name>hadoop.tmp.dir</name>
  <value>/app/hadoop/tmp</value>
</property>

<property>
  <name>fs.default.name</name>
  <value>hdfs://localhost:54310</value>
</property>

step 5 : edit mapred-site.xml

  <property>
      <name>mapreduce.framework.name</name>
      <value>yarn</value>
    </property>

step 6 : edit hdfs-site.xml

<property>
  <name>dfs.replication</name>
          <value>1</value>
</property>

<property>
  <name>dfs.name.dir</name>
  <value>file:///home/hduser/hadoopdata/hdfs/namenode</value>
</property>

<property>
  <name>dfs.data.dir</name>
  <value>file:///home/hduser/hadoop/hadoopdata/hdfs/datanode</value>
</property>

step 7 : edit yarn-site.xml

<property>
   <name>yarn.nodemanager.aux-services</name>
   <value>mapreduce_shuffle</value>
</property>

finally format your hdfs (You need to do this the first time you set up a Hadoop cluster)

$ /usr/local/hadoop/bin/hadoop namenode -format

Hbase Configuration:

edit you hbase-site.xml :

<property>
  <name>hbase.rootdir</name>
  <value>hdfs://localhost:54310/hbase</value>
</property> 

<property>
   <name>hbase.cluster.distributed</name>
   <value>true</value>
</property>

<property>
   <name>hbase.zookeeper.quorum</name>  
   <value>localhost</value>
</property>

<property>   
  <name>dfs.replication</name>   
  <value>1</value>    
</property>

 <property>       
  <name>hbase.zookeeper.property.clientPort</name>  
  <value>2181</value>                                                                                 
 </property>

 <property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/usr/local/hbase/zookeeper</value>   
 </property>                                                                                                                          

Hope this helps you

Answer 2

After sticking with the problem for more than 3 days (maybe it's from my misunderstanding the concept), I can fix the problem by adding HADOOP_CLASSPATH (like what I did when setting up the pseudo-distribute in hadoop-env) into the yarn-env.

I have no idea much in detail. But, yeah, hope this may be able to help someone in the future.

Cheers.

Answer 3

I was using Spark on Yarn and was getting the same error. Actually, the spark jar had a internal dependency of hadoop-client and hadoop-mapreduce-client-* jars pointing to older 2.2.0 versions. So, I included these entries in my POM with the Hadoop version that I was running and did a clean build.

This resolved the issue for me. Hope this helps someone.
