meng gong commented on MAPREDUCE-4886:
--------------------------------------
1.These failures are caused for this TestCase opens too many files, when the
default file handles per thread in linux is 1024. Modify the limit of
environment value “nrfile“ to 16384. This test case can be build successfully.
2.We can close this jira
Or Every time users want to run "ant test-contrib", we can add a task to
check the system environment and report warning when some values can't reach
the minimum requirement of these Junit tests.
