Konstantin Shvachko commented on HDFS-2498:
-------------------------------------------
You are right, Todd. I'll incorporate.
I see that even when TestParallelRead succeeds (rather rarely) on Jenkins its
running time is around 14 minutes. While on my linux box it completes in less
than 20 seconds.
And in the log attached I see
{code}
[junit] 2011-10-24 19:58:35,474 INFO hdfs.TestParallelRead
(TestParallelRead.java:runParallelRead(269)) - === Report: 16 threads read
941298 KB (across 1 file(s)) in 550.051s; average 1711.292225629987 KB/s
{code}
So the second runParallelRead() is actually running more than 9 minutes
(550.051s). Again, on my box it completes in only 2-3 seconds.
Is it possible that because ReadWorker,run() does not catch Error (only
Exception) the thread cannot complete?
