Connection error while usinh HBase client API for pseudodistrbuted mode
Hi,
For development purpose, I have set up HBase in pseudodistributed mode.
I have following line in hbase-env.sh file
export HBASE_MANAGES_ZK=true
HBase shell works fine. But client API is not working.
My client code is as follows
Configuration config = HBaseConfiguration.create();
config.set("hbase.zookeeper.quorum", "10.78.32.131");
config.setBoolean("hbase.cluster.distributed", false);
HBaseAdmin admin = new HBaseAdmin(config);
admin.isMasterRunning();
System.out.println(admin.getClusterStatus().getHBaseVersion());
I am getting java.net.ConnectException: Connection refused: no further
information.
Any idea, how it can be fixed. Please let me know. Thanks!!

Anand

It would be better to start fresh..Add these props in your core-site.xml file -
<property>
<name>fs.default.name</name>
<value>hdfs://localhost:9000</value>
</property>
<property>
<name>hadoop.tmp.dir</name>
<value>/home/mohammad/hdfs/temp</value>
</property>
<property>
In hdfs-site.xml -
<property>
<name>dfs.name.dir</name>
<value>/home/mohammad/hdfs/name</value>
</property>
<property>
<name>dfs.data.dir</name>
<value>/home/mohammad/hdfs/data</value>
</property>
<property>
<name>dfs.datanode.max.xcievers</name>
<value>4096</value>
</property>
<property>
<name>dfs.replication</name>
<value>1</value>
</property>
in hbase-site.xml -
<name>hbase.rootdir</name>
<value>hdfs://localhost:9000/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>
<description>Property from ZooKeeper's config zoo.cfg.
The port at which the clients will connect.
</description>
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/home/mohammad/hbase/zookeeper</value>
<description>Property from ZooKeeper's config zoo.cfg.
The directory where the snapshot is stored.
</description>
</property>
Also change this line in hbase-env.sh -
export HBASE_REGIONSERVERS=/home/mohammad/hbase-0.90.4/conf/regionservers

That did not help. Still I dont see hbase master and zookeeper processes. I
am thinking of starting everything from scratch. Any suggestions?

Change the value of fs.default.name to "hdfs://localhost:8020" and

Re: Connection error while usinh HBase client API for
pseudodistrbuted mode
Posted by AnandaVelMurugan Chandra Mohan <an...@gmail.com>.
For starting Hbase master manually
I did "cd" to <HBASE_HOME>\bin
Then did ./hbase master start
Contents of my hbase-site.xml

I could do HDFS operations like get, put in Hadoop. I could also create and
list tables in Hbase shell.

What do you mean by "I tried starting Hbase master manually and I got
this error."??..By manually do you mean through the shell??How were
you trying to do it earlier??And if possible could you please post the
modified core-site.xml and hbase-site.xml files.

Re: Connection error while usinh HBase client API for
pseudodistrbuted mode
Posted by AnandaVelMurugan Chandra Mohan <an...@gmail.com>.
Thanks for the link.
I followed the link and fixed my hdfs url too.
But when I start hbase, hbase master and zookeeper processes are not
starting
I tried starting Hbase master manually and I got this error.
ERROR master.HMasterCommandLine: Failed to start master
java.io.IOException: CRC check failed
Do you have any idea?

Re: Connection error while usinh HBase client API for
pseudodistrbuted mode
Posted by Mohammad Tariq <do...@gmail.com>.
Not a prob..I was expecting this after looking at the config
file..First of all your "hbase.rootdir" property must contain the
"complete" value of the "fs.default.name" property in your hadoop's
"core-site.xml" file.(This includes "port no" also)..After that just
add the following properties in your hbase-site.xml file and let me
know if it is works for you.
<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>
<description>Property from ZooKeeper's config zoo.cfg.
The port at which the clients will connect.

</property>

Re: Connection error while usinh HBase client API for

Posted by AnandaVelMurugan Chandra Mohan <an...@gmail.com>.
Sorry. I tried list and it returned 0 as no table exists. Then I posted
this question.
Now when I try create table now, shell is hanging and I get following
exception
org.apache.hadoop.hbase.client.RetriesExhaustedException: Failed setting up
proxy interface org.apache.hadoop.hbase.ipc.HRegionInterface to localhost/
127.0.0.1:39591
So I feel issue is with HBase and not with client API. Let me fix this
issue and try client API.
Meanwhile, do you have any idea on this issue?

config.set("hbase.master", "localhost:60000");
