Subject ERROR 22:59:00,329 Error in ThreadPoolExecutor
Date Thu, 15 Jul 2010 17:43:28 GMT
I am trying to set up a 3 node cluster. RF=3 and CL=1 for most of the request. The initial
seeding took about 1 hour to complete which loaded each node with 2G of data. After the seeding
completed, one node started having this exception and hung. Read/Write with CL=ALL timed out
but CL=QUORUM was fine. I restarted the node and the problem went away. But after 3 hours,
same scenario reappeared. Any idea? Any workaround? Thanks. -Claire
