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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
