Tsz Wo (Nicholas), SZE commented on HADOOP-3694:
------------------------------------------------
> The failed test last night
> (TestFileCreation#testClientTriggeredLeaseRecovery) is unrelated. The problem
> there is that it uses Thread.interrupt() to stop threads that are writing to
> HDFS, but that's not reliable, since DFSClient catches and ignores
> InterruptedException in many places (which is a bug). So this test fails
> sporadically.
+1 on adding a boolean for stopping the SlowWriter threads.
> if MiniDFS startup time could be improved, testing time would be reduced

> Its taking me 140 minutes to run a test build; looking into the test results
> its the 20s startup delay of every MiniDFS cluster that is slowing things
> down. If we could find out why it is taking so long and cut it down, every
> test case that relied on a cluster would be speeded up.
