Question

Below is the create DDL. With this I get error. Any idea what is wrong? The full error log is as;

FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask.
org.apache.hadoop.hive.ql.metadata.HiveException: Error in loading storage handler.
org.apache.hadoop.hive.cassandra.CassandraStorageHandler

        CREATE EXTERNAL TABLE mktg_contact_general_info_comp_hive_incr 
        (
        person_party_id string,
        org_party_id            string,

        last_source_system      string,
        introduction_source_system     string,

错误清除说，它无法在运行时环境中找到类。

org.apache.hadoop.hive.cassandra.CassandraStorageHandler

而是尝试用

替换表创建查询中的那个

org.apache.hadoop.hive.cassandra.cql.CqlStorageHandler

如果那也失败了，那么你只是缺少hive-cassandra jar

Error in loading storage handler.org.apache.hadoop.hive.cassandra.CassandraStorageHandler
