Shubham Chaurasia updated HIVE-23022:
-------------------------------------
Description:
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 some table which contains
complex types (struct nested in list to be specific) and number of rows in
table is more than default (1024) batch/vector size.
