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.
