Hi @sind65 

Could you please clarify few things before proceeding any solutions:

1. Are you using CDP or CDH?

2. How are you submitting the spark job? 

3. Are you using kinit or you have specified principal/keytab?

4. Have you followed the following documentation to setup and run the sample example

HI Ranga,

Thank you for the reply, Please find my answers below:

1. We are working on CDP.

2. Spark submit is submitted with the cache file, property files and java options. Please let me know if i need to share more details. 

3. We are using principal and kerberos cache

4. The below article has been followed and the configuration i have validated

We are using "authentication=SPENGO" and the phoenix string(phoenixurl in code) is as below:

<ZK>:2181;authentication=SPNEGO/hbase-secure:<principal>:<cache>

We are using the above phoenix string with the code below:

dataset.write().format("org.apache.phoenix.spark").mode(SaveMode.Overwrite)
.option("table",tableName.concat(row.get(0).toString()))
.option("zkUrl",phoenixurl)
.save();

The same above is working fine on CDP, when we migrate the same app on the hadoop instance enabled with ozone. we have above issue w.r.t kerberos.

Please support.. Looking forward for your suggestion
