Chao Sun created HIVE-14531: ------------------------------- Summary: Support deep nested struct for INSERT OVER DIRECTORY Key: HIVE-14531 URL: https://issues.apache.org/jira/browse/HIVE-14531 Project: Hive Issue Type: Bug Components: Query Processor, Serializers/Deserializers Affects Versions: 2.2.0 Reporter: Chao Sun
Currently if we do something similar to: {code} INSERT OVERWRITE DIRECTORY <dir> SELECT * FROM <table_with_deeply_nested_columns> {code} Then Hive may fail with error message like this: {code} Error: Error while compiling statement: FAILED: SemanticException org.apache.hadoop.hive.serde2.SerDeException: Number of levels of nesting supported for LazySimpleSerde is 7 Unable to work with level 8. Use hive.serialization.extend.nesting.levels serde property for tables using LazySimpleSerde. (state=42000,code=40000) {code} It seems there's no way to set serde properties in this case. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
