HBase 1.2.1 standalone in Docker unable to connect
<p>I want to connect to HBase running in standalone in a docker, using Java and the HBase API</p>

<p>I use this code to connect :</p>

<pre><code>Configuration config = HBaseConfiguration.create();
config.set("hbase.zookeeper.quorum", "163.172.142.199");
config.set("hbase.zookeeper.property.clientPort","2181");
HBaseAdmin.checkHBaseAvailable(config);
</code></pre>

<p>Here is my /etc/hosts file</p>

<pre><code>127.0.0.1   localhost
XXX.XXX.XXX.XXX hbase-srv
</code></pre>

<p>Here is the /etc/hosts file from my docker (named hbase-srv)</p>

<pre><code>XXX.XXX.XXX.XXX hbase-srv
</code></pre>

<p>With this configuration, I get a connection refused error :</p>

<pre><code> INFO | Initiating client connection, connectString=163.172.142.199:2181 sessionTimeout=90000 watcher=hconnection-0x6aba2b860x0, quorum=163.172.142.199:2181, baseZNode=/hbase

</code></pre>

<p>However, if I remove the lines <code>XXX.XXX.XXX.XXX hbase-srv</code> from both <code>/etc/hosts</code> files I get the error <code>unknown host : hbase-srv</code></p>

<p>I have also checked, I can successfully <em>telnet</em> to my hbase docker on the client port.</p>

<p>On the docker, all the ports used by HBase are opened and binded to the same number (60000 on 60000, 2181 on 2181, etc).</p>

<p>I also wanted to add that all was fine when I used this configuration on localhost.</p>

<p>If you can't give me an answer to my problem, could you at least give me a procedure to deploy a standalone hbase on a docker.</p>

<p>UPDATE : Here is my Docker file</p>

<pre><code>FROM java:openjdk-8

ADD hbase-1.2.1 /hbase-1.2.1

WORKDIR /hbase-1.2.1
# ZooKeeper
EXPOSE 2181

# HMaster
EXPOSE 60000

# HMaster Web
EXPOSE 60010

# RegionServer
EXPOSE 60020

# RegionServer Web
EXPOSE 60030

EXPOSE 16010

RUN chmod 755 /hbase-1.2.1/bin/start-hbase.sh
CMD ["/hbase-1.2.1/bin/start-hbase.sh"]
</code></pre>

<p>My HBase shell is working, I also tried to open the port using iptables for tcp and udp but still the same problem</p>
