Aihua Xu updated HIVE-9500:
---------------------------
Description:
Customer has deeply nested avro structure and is receiving the following error
when performing queries.
15/01/09 20:59:29 ERROR ql.Driver: FAILED: SemanticException
org.apache.hadoop.hive.serde2.SerDeException: Number of levels of nesting
supported for LazySimpleSerde is 23 Unable to work with level 24
Currently we support up to 24 levels of nested structs when
hive.serialization.extend.nesting.levels is set to true, while the customers
have the requirement to support more than that.
It would be better to make the supported levels configurable or completely
removed (i.e., we can support any number of levels).
