[jira] [Commented] (HIVE-80) Add testcases for concurrent query execution
[ https://issues.apache.org/jira/browse/HIVE-80?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanelfocusedCommentId=13249465#comment-13249465 ] Carl Steinbach commented on HIVE-80: HiveServer can't support concurrent connections due to a limitation of the current HiveServer Thrift API. There's a proposal for a new HiveServer2 Thrift API which fixes these problems located here: https://cwiki.apache.org/confluence/display/Hive/HiveServer2+Thrift+API Add testcases for concurrent query execution Key: HIVE-80 URL: https://issues.apache.org/jira/browse/HIVE-80 Project: Hive Issue Type: Test Components: Query Processor, Server Infrastructure Reporter: Raghotham Murthy Assignee: Carl Steinbach Priority: Critical Labels: concurrency Attachments: hive_input_format_race-2.patch Can use one driver object per query. -- This message is automatically generated by JIRA.

Otherwise, you will see this: ERROR in runJob org.apache.thrift.transport.TTransportException: java.net.ConnectException: Connection refused Has anyone used multiple hiveservers for managing multiple connections? (something like Amazon's cloud map/reduce, where they spin up a temporary instance?)

From what i read on the Hive wiki ( http://wiki.apache.org/hadoop/Hive/HiveServer ) it appears that the hive server is single threaded. I might be mistaking, but this is what i understand from that text: if i launch 2 requests from my client towards the hive server, the hive server will not handle them in parallel and the hadoop requests done by hive itself will run one after another, not in parallel. Is this right? If (hopefully) not :) , could someone please clarify that for me, if possible? Thank you.
