Description

Avoid batch reading (set with hive.parquet-batch-read-optimization-enabled=true) of nested decimals as this reader is not implemented.

Reading a nested decimal column defined as:

as_array_big_decimal: OPTIONAL F:1
.list:                REPEATED F:1
..element:            OPTIONAL INT32 L:DECIMAL(1,0) R:1 D:3

without this PR results in the following error:

java.lang.UnsupportedOperationException: com.facebook.presto.common.block.IntArrayBlock
