---------------------------------------
Summary: HiveServer2: Use user supplied fetch size to determine
#rows serialized in tasks
Key: HIVE-14901
URL: https://issues.apache.org/jira/browse/HIVE-14901
Project: Hive
Issue Type: Sub-task
Reporter: Vaibhav Gumashta
Currently, we use {{hive.server2.thrift.resultset.max.fetch.size}} to decide
the max number of rows that we write in tasks. However, we should ideally use
the user supplied value (which can be extracted from the
ThriftCLIService.FetchResults' request parameter) to decide how many rows to
serialize in a blob in the tasks. We should however use
{{hive.server2.thrift.resultset.max.fetch.size}} to have an upper bound on it,
so that we don't go OOM in tasks and HS2.
