Deng Changchun commented on SPARK-16643:
----------------------------------------
Thank you for response.
I think this problem is totally different from
https://issues.apache.org/jira/browse/SPARK-12240, even through they both
reported FileNotFoundException.
For SPARK-12240, I can solve it through setting ulimit. Come back to this
problem, I have setted ulimit unlimited, the error info is not "too many open
files", just "that file or directory doesn't exist". So I don't think they are
the similar problem.
By the way, I will try with a more recent version.
