@attilabukor Hi, Thank you for your comment. Yesterday, I got a comment from HaoHao about this issue. The issue not being able to create KUDU table on CDH 6.3.2 is related to remote HMS configuration in hive-site.xml KuduTable.java ( on CDH 6.3.2 ) has a logic validating if `hmsuris` is null or empty. If `hmsuris` is empty or null, it raises exception and fails. This has been fixed on master branch, but I'm not sure if this fix will be delivered with CDH 6.3.3 Can you confirm if the fix is shipped with CDH 6.3.3? Here is the bug report ticket. https://issues.apache.org/jira/browse/IMPALA-8974 Gatsby

My current environment is CDH 6.3.2 Impala v3.2.0-cdh6.3.2 kudu 1.10.0-cdh6.3.2 Somehow, creating table with kudu storage gives IllegalArgumentException. It was ok with kudu 1.7.0-cdh5.16.2 CREATE TABLE test_mlee ( id BIGINT, name STRING, PRIMARY KEY(id) ) PARTITION BY HASH PARTITIONS 16 STORED AS KUDU ERROR: IllegalArgumentException: null Any comment is appreciated Thank you in advance.

have you checked the tested/supported OpenJDK list? https://docs.cloudera.com/documentation/enterprise/6/release-notes/topics/rg_java_requirements.html#concept_hzw_zyl_rcb JDK 8u40, 8u45, 8u60, and 8u242 are not supported due to JDK issues impacting CDH functionality:

Hello, Thank you for reading this question. Recently, one of Hadoop clusters we have has been upgraded to Hadoop 3.0 ( CDH 6.3.2 ). I'm curious that the copied data from Hadoop 3.0 ( by distcp ) can be used by Hadoop 2.6 cluster. I was able to distcp from Hadoop 3.0 cluster to Hadoop 2.6, but I found out this document. https://hadoop.apache.org/docs/r3.0.3/hadoop-distcp/DistCp.html#Copying_Between_Versions_of_HDFS Can you give me some comment for this? Thank you very much in advance.
