Using HBql Zookeeper will not attempt to authenticate using SASL

Question

I wanted to test the HBql for simple usage of HBase.I followed the steps described on HBql Website ( http://www.hbql.com/installation.html ). At the end when typing the version-command in HBql-console to verify my installation, i get the following messages:

These messages were only printed when using HBql console. HBase work successfully in distributed mode, storing data in HDFS on Debian squeeze.Do you need more information? What mistakes i did? Why SASL is here needed and in general situation like HBase shell not?

maybe some important config:

hbase-env.sh

hbase_manage_zk=true

hbase-site.xml

    <property>
      <name>hbase.zookeeper.property.clientPort</name>
      <value>2222</value>
    </property>
    <property>
      <name>hbase.zookeeper.quorum</name>
      <value>master</value>
    </property>
    <property>
      <name>hbase.zookeeper.property.dataDir</name>
      <value>/usr/local/zookeeper</value>
    </property>

Thank You!

Answer 1

I have installed HBase recently with Nutch and Solr and had a similar problem. I am not sure if exactly the same and unfortunately I do not have the logs any more but it was definitely connection related.

It turned out that the default connection limit for ZooKeeper was too low and increasing this value in hbase-site.xml solved it for me:

<property>
    <name>hbase.zookeeper.property.maxClientCnxns</name>
    <value>1000</value>
</property>

I had the same problem. This answer assumes you work on linux and edited your etc/hosts file accordingly ( https://stackoverflow.com/a/13540883/1607022 )

The client port number for zookeeper must be same in configuration files of HBase and whatever you use on top of it. Solution is; (in my case HBASE 0.90.4 with GORA 0.3) check your hbase-default.xml under your HBASE_HOME/src/main/resources:

<name>hbase.zookeeper.property.clientPort</name>
<value>2181</value>

And there should be a hbase-site.xml under HBql:

<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>

Port numbers should be the same.
