linwukang updated HADOOP-8718:
------------------------------
Description:
org.apache.hadoop.fs.viewfs.InodeTree.createLink(...) may throw java.lang.ArrayIndexOutOfBoundsException as breakIntoPathComponents(src) may return null. this happened when run the test case of viewfs on my jenkins server. In my situation, "/" is passed into breakIntoPathComponents() as its param "src".
Here is the trace:
