Hi, I am wondering if anyone has experienced this problem. Sometimes when I ran a job, a few map tasks (often just one) hang in the initializing phase for more than 3 minutes (it normally finishes in a couple seconds). They will eventually finish, but the whole job is slowed down considerably. The weird thing is that the slow task is not deterministic. It doesn't always occur and if does, can occur on any split and on any host.
I'd appreciate any help on understanding this. Jun IBM Almaden Research Center K55/B1, 650 Harry Road, San Jose, CA 95120-6099 [EMAIL PROTECTED] (408)927-1886 (phone) (408)927-3215 (fax)
