> 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.
