Walter Su commented on HDFS-9323:
---------------------------------
In the test case, dnIndex is streamers' index, also is block index.
{noformat}
idx0 idx1 idx2 idx3 idx4 idx5 idx6 idx7 idx8
* * * * * * * * *
* * * *(killPos)
{noformat}
idx0,5,6,8 are boundary, idx3,4 are boundary too. So it doesn't worth much to
skip some index.
The patch LGTM. +1 pending jenkins.

> (testDatanodeFailureRandomLength). We should randomize all the tests.
