> 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).
