> 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
> Components: HiveServer2, JDBC, ODBC
> Affects Versions: 2.1.0
> Reporter: Vaibhav Gumashta
> Assignee: Norris Lee

>
> 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.
