Using HBql Zookeeper will not attempt to authenticate using SASL

I wanted to test HBql for simple use of HBase.I followed the steps described on the HBql website ( http://www.hbql.com/installation.html ). At the end of entering the version command in the HBql console, to check my installation, I get the following messages:

These messages were printed only when using the HBql console. HBase successfully works in distributed mode, storing data in HDFS during Debian compression. Do you need more information? What mistakes have I made? Why is SASL needed here, and in general, like the HBase shell, no?

there may be some important configuration:

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>

Thanks!

I recently installed HBase with Nutch and Solr and had a similar problem. I'm not sure exactly the same, and unfortunately I no longer have the logs, but this is definitely connected.

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

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

I had the same problem. This answer assumes that you are working on linux and have accordingly edited your etc / hosts file ( fooobar.com/questions/1441844 / ... )

The client port number for zookeeper should be the same in the HBase configuration files and what you use on top of it. There is a solution; (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 under HBql there should be hbase-site.xml:

 <property> <name>hbase.zookeeper.property.clientPort</name> <value>2181</value> <description>Property from ZooKeeper config zoo.cfg. The port at which the clients will connect. </description> </property>

Port numbers must be the same.
