This bug is a duplicate of HIVE-3253.
> LazySimpleSerDe should support more levels of nested structures

> [LazySimpleSerDe.initSerdeParams|https://github.com/apache/hive/blob/trunk/serde/src/java/org/apache/hadoop/hive/serde2/lazy/LazySimpleSerDe.java#L208]
> hard-codes the level of separators to 8, causing structures with more than
> that level of nestedness to fail.
> Doubling this value to 16 allowed me to read an extremely nested structure.
> This code was added in HIVE-337 and reading through the jira I can't see a
> reason 8 was chosen, other than it seemed like a reasonable value. Any reason
> not to double this, or allow the user to configure via a property?
