Hi Hadoopers,
we are experiencing a lot of Could not obtain block / Could not get
block locations IOExceptions when processing a 400 GB large Map/Red job
using our 6 nodes DFS MapRed (v. 0.16.4) cluster. Each node is
equipped with a 400GB Sata HDD and running Suse Linux Enterprise
Edition.
Hi dhruba,
we are running the latest Sun Java 6u10-beta, and the namenode runs with
25 threads on a quad core machine.
Cu on the 'net,
Bye - bye,
André èrbnA
