Can you check your input format ? Can you check the value of the parameter : hive.input.format ?
Can you send all the parameters ? Thanks, -namit -----Original Message----- From: Tim Sell [mailto:[email protected]] Sent: Tuesday, February 23, 2010 11:00 AM To: [email protected] Subject: Hive jobs only run with 1 map task We just upgraded to hadoop 0.20 (from hadoop 0.18), impressively our same hive package kept working against the new hadoop setup. Since the upgrade every hive starts with only 1 map task though. Even after setting it with eg: set mapred.map.tasks=32; We recompiled our hive setup against hadoop 0.20 and still get the same issue. Any suggestions for something obvious we might have missed? ~Tim.
