Question: I use ubuntu 12.04, after download and un-tar hbase-0.94.1.jar. I started hbash in standalone mode by the following command

```
user@ubuntu:~/temp/hbase-0.94.1$ bin/start-hbase.sh 
starting master, logging to /home/user/temp/hbase-0.94.1/bin/../logs/hbase-user-master-ubuntu.out

```

but when I try to access hbash status UI on 

```
http://localhost:60010

```

, I got "Unable to connect". 

Thanks.

Answer: 
First check "**hbase-hduser-master-ubuntu.log**" file from **logs** folder of your hbase installed path

**if you are getting following error**

2014-09-07 20:22:24,505 ERROR [main] master.HMasterCommandLine: Master exiting
java.lang.RuntimeException: **HMaster Aborted**
 at org.apache.hadoop.hbase.master.HMasterCommandLine.startMaster(HMasterCommandLine.java:194)
 at org.apache.hadoop.hbase.master.HMasterCommandLine.run(HMasterCommandLine.java:135)

 at org.apache.hadoop.hbase.util.ServerCommandLine.doMain(ServerCommandLine.java:126)
 at org.apache.hadoop.hbase.master.HMaster.main(HMaster.java:2794)

compare **core-site.xml** of ***Hadoop*** with **hbase-site.xml** of ***hbase***. hdfs URL should be same in both file

***core-site.xml***

```
 <configuration>
    <property>
        <name>fs.default.name</name>
        <value>hdfs://192.168.203.130:9000</value>
    </property>
 </configuration>

```

***hbase-site.xml***

```
 <property>
    <name>hbase.rootdir</name>
    <!-- <value>hdfs://localhost:9000/hbase</value> -->
    <value>hdfs://192.168.203.130:9000/hbase</value> 
    <description>The directory shared by RegionServers.
    </description>
 </property>

```
Please try accessing HBase master web-ui with <http://localhost:16010>
