Error: Could not find or load main class
org.apache.hadoop.hbase.util.GetJavaProperty
I downloaded the latest stable hbase 0.94.8 and followed the instructions for
getting started.
However, when I try to run hbase I get the following.
/ubuntu:~/dev/hadoop/hbase-0.94.8$ ./bin/start-hbase.sh Error: Could not
find or load main class org.apache.hadoop.hbase.util.GetJavaProperty Error:
Could not find or load main class
org.apache.hadoop.hbase.util.GetJavaProperty starting master, logging to

Error: Could not find or load main class
org.apache.hadoop.hbase.util.GetJavaProperty localhost: ssh: connect to host
localhost port 22: Connection refused/
I have Java 7 installed and run hadoop and hive on my local box for testing
with no issues.
/@ubuntu:~/dev/hadoop/hbase-0.94.8$ java -version
java version "1.7.0_21"
Java(TM) SE Runtime Environment (build 1.7.0_21-b11)
Java HotSpot(TM) 64-Bit Server VM (build 23.21-b01, mixed mode)
/
Does HBase not run on Java 7?

If you have simply downloaded and extracted HBase the same way I did
below, then it's not coming from HBase since it's working for everyone
else.
There might be something with your installation/configuration.
Do you have any HADOOP_CLASSPATH or HBASE_CLASSPATH declared? Is so,
can you remove it and retry?
Also, can you try this command?
HADOOP_IN_PATH= $(PATH="${HADOOP_HOME:-${HADOOP_PREFIX}}/bin:$PATH"
which hadoop 2>/dev/null); echo $HADOOP_IN_PATH
The only place with GetJavaProperty is called is there:
HADOOP_JAVA_LIBRARY_PATH=$(HADOOP_CLASSPATH="$CLASSPATH"
${HADOOP_IN_PATH} org.apache.hadoop.hbase.util.GetJavaProperty
java.library.path 2>/dev/null)
and this is only called if the command above is not null.
So I guess he command above is not null for you, else your error
message will not be displayed.
Can you also echo $HADOOP_CLASSPATH and CLASSPATH?
Thanks,
JM

It's a packaged version, but I have no problems running HIVE and Hadoop
locally using it.

No, it's not sshd related.
Is it a packaged version of the JDK? Or a tar.gz version? If it's a
packaged version, can you try with the tar.gz version? I had issues in
the past with the packaged one...

There is something wrong with your configuration.
Here is what I get on my side:

What's the result of echo $JAVA_HOME on you system? Also are you
running open JDK? Or Oracle JDK?

Can you try to start it right after the extraction? Don't even modify anything.
Extract, export JAVA_HOME, run.
If this is working, we will take a look at why you configuration below
is not working.
You can also update the JAVA_HOME in hbase-env.sh.

Hi Jean-Marc,
I downloaded the tarball, extracted it, modified the conf/hbase-site.xml as
follows:
/
<configuration>
<property>
<name>hbase.rootdir</name>
<value>/home/psamtani/dev/hadoop/hbase-data/hbase</value>
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/home/psamtani/dev/hadoop/hbase-data/zookeeper</value>
</property>
</configuration>
/
And then tried to start hbase

Hi,
HBase should be working with JDK 7, however it's so far only
supporting JDK 6. The issue you are facing below is mode probably not
JDK related. Can you describe the steps you followed?
