> 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).
