> Arrow deserializer - {{org.apache.hadoop.hive.ql.io.arrow.Deserializer}} in
> some cases does not set the size of hive vector correctly. Size of hive
> vector should be set at least equal to arrow vector to be able to read
> (accommodate) it fully.
> Following exception can be seen when we try to read (using
> {{LlapArrowRowInputFormat}} ) some table which contains complex types (struct
> nested in array to be specific) and number of rows in table is more than
> default (1024) batch/vector size.
> {code:java}
> Caused by: java.lang.ArrayIndexOutOfBoundsException: 1024
