Affects Version/s: 0.20.205.0, 0.23.0
Fix Version/s: None
Since upgrading Jetty from 6.1.14 to 6.1.26 we've had a ton of HTTP-related issues, including:
- Much higher incidence of fetch failures
- A few strange file-descriptor related bugs (eg MAPREDUCE-2389)
- A few unexplained issues where long "fsck"s on the NameNode drop out halfway through with a ClosedChannelException
Stress tests with 10000Map x 10000Reduce sleep jobs reliably reproduce fetch failures at a rate of about 1 per million on a 25 node test cluster. These problems are all new since the upgrade from 6.1.14.
