Below is persistance file
As you can see "update" in "kundera.ddl.auto.prepare" . I'm expecting all the tables to be created.
Any suggestion towards this issue will help me a lot.
Hi @jeevitesh,
Use kundera-hbase-v2 module instead of kundera-hbase. Use this dependency:
<dependency>
<groupId>com.impetus.kundera.client</groupId>
<artifactId>kundera-hbase-v2</artifactId>
<version>${kundera.version}</version>
</dependency>
Check Kundera with HBase for more details.

I have done those changes still error persists. I have sent(by mail : gmail) a sample project where you can reproduce the issue. kindly help us in this regard.
Hi @jeevitesh,
First of all, use only latest version of Kundera and kundera-hbase-v2 module.
We tested it with 1.2, 1.0 & 0.96 HBase versions.
kundera-elastic-search is needed if you want to store indexes in elasticsearch along with data in HBase. I recommend start with only kundera-hbase-v2. Once you are able to perform simple queries then you can use kundera-elastic-search for aggregation queries.
It looks like a connection problem. Start without using schema generation feature and create schema at your own.

Hi Devendar, Thanks for the response.. Currently there are no store indexes.. "Start without using schema generation feature" not able to understand this can kindly explain thnaks jeevitesh

Hi @jeevitesh,
You added schema auto-generation property in persistence.xml
<property name="kundera.ddl.auto.prepare" value="update" />
This is creating HTable for your entity in HBase. Since you are getting the issue in HBaseSchemaManager, so I recommended to create HTable yourself and remove that property from the persistence.xml.
