-------------------------------
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.
