Hi @tallamohan ,

I see that the "Load data inpath" statement is failing with a NPE:

Caused by: java.lang.NullPointerException
at org.apache.hadoop.hive.ql.ddl.DDLSemanticAnalyzerFactory.<clinit>(DDLSemanticAnalyzerFactory.java:79)

...

at com.teradata.connector.common.tool.ConnectorJobRunner.runJob(ConnectorJobRunner.java:210)

Has this worked before in your cluster?

Is this a new integration of Teradata with Hive / CDP?

The NPE happens at a phase where the DDLSemanticAnalyzerFactory is searching for subclasses of BaseSemanticAnalyzer (which extend BaseSemanticAnalyzer) under the "org.apache.hadoop.hive.ql.ddl" package. Do you have custom analyzer classes under that package? Do they have the "@DDLType" annotation? See 

https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/ddl/database/desc/DescDatabaseAnalyzer.java#L35

as an example.
That annotation is likely missing, causing an NPE. 

If not, please check the classpath of HS2 for old / custom jars, which may still have some classes under the "org.apache.hadoop.hive.ql.ddl" package.

 

Hope this helps,

Best regards

Hi Miklos,

= = = = = = = = = = = = = = = = = = = =

Yes, it worked in CDP 7.1.7.

When I upgraded my cluster to CDP 7.1.7 SP1 it failed.

 

Is this a new integration of Teradata with Hive / CDP?

= = = = = = = = = = = = = = = = = = = = = = = = = = = =

No, existing tool (TDCH)

 

Do you have custom analyzer classes under that package? Do they have the "@DDLType" annotation?

= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = 

No

 

Attached below sample MapReduce job. (Main.java)

This job worked fine in CDP 7.1.7 but failed in CDP 7.1.7 SP1

 

Thanks,

Mohan

Have you reviewed the classpath of the HS2 and all the jars?

$JAVA_HOME/bin/jinfo <hs2_pid> | grep java.class.path

Do they have some classes under the "org.apache.hadoop.hive.ql.ddl" package?


The attached code does not work on my cluster (it is missing some tez related configs). What configuration does it require?

Hi @tallamohan 

The direct usage of the Hive classes (CliSessionState, SessionState, Driver) in the provided code falls under the "Hive CLI" or "Hcat CLI" access, which is not supported in CDP:

https://docs.cloudera.com/cdp-private-cloud-upgrade/latest/upgrade/topics/hive-unsupported.html

Please open a case on MyCloudera Support Portal to get that clarified.

The recommended approach would be to use beeline and access the Hive service through HiveServer2.

 

Best regards

 Miklos
