Subject Re: zookeeper is null
Date Thu, 08 Dec 2016 11:49:40 GMT
 I started this project a few week ago.Thus I use only 2 computer at the
moment (probably more afterward when it works).

I have change the configuration to:
<configuration>
    <property>
    <name>hbase.cluster.distributed</name>
    <value>true</value>
    </property>
    <property>
    <name>hbase.rootdir</name>
    <value>hdfs://fontana-04:9000/opt/hbase</value>
    </property>
    <property>
    <name>hbase.security.authentication</name>
    <value>simple</value>
    </property>
    <property>
    <name>hbase.ipc.client.fallback-to-simple-auth-allowed</name>
    <value>true</value>
    </property>
    <property>
        <name>hbase.zookeeper.quorum</name>
    <value>localhost:2181</value>
    </property>
    <property>
        <name>hbase.client.keyvalue.maxsize</name>
        <value>0</value>
    </property>
   <property>
        <name>zookeeper.znode.parent</name>
        <value>/hbase</value>
    </property>
</configuration>

and i have remove fontana-03 to slave, regionserver and quorum for more
clarity.

Did i have make something wrong in other file or it was zookeeper?


the 2 error was:
WARN zookeeper.ClientCnxn: Session 0x0 for server null, unexpected error,
closing socket connection and attempting reconnect

zookeeper.ClientCnxn: Opening socket connection to server localhost/
127.0.0.1:2181. Will not attempt to authenticate using SASL (unknown error)
