Huafeng Wang commented on HDFS-12497:
-------------------------------------
Hi [~Sammi] [~andrew.wang], I found decreasing the number of stripes of a block
cannot totally solve the timeout issue. It will also impact the original test
cases. In original {{TestDFSStripedOutputStreamWithFailure}}, it generates a
list of 216(3 * 4 * 6 * 3) different file lengths and the subclass will choose
different file length to run the test. Setting stripes of a block to 2 will
make some test cases actually invalid.
So I proposed to decrease the cell size in these test cases. I'll give it a try
and see whether the timeout issue can be eliminated.
