-------------------------------

             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.
