Wei-Chiu Chuang commented on HDFS-10935:
----------------------------------------

I have two local Hadoop repo, one is built with native isa-l lib and the other is not. The one without the native lib failed while the other passed. It seems java based codec doesn't work as expected.

I also have other tests where if I specifically corrupt 1, 2 or 3 strips out of 9, it does not recover if hadoop is built without native lib.

> On my Mac, TestFileChecksum has been been failing since HDFS-10460. However, the jenkins jobs have not reported the failures. Maybe it's an issue with my Mac or JDK.
> 9 out of 21 tests failed.
