It is possible that I fix the issue in 0.20 without breaking the
compatibility. But I am worried about the code stability if we take
this approach. The pipeline code is such a critical and fragile part
of HDFS. Currently I depend on the extensive pipeline fault
injection tests created in 0.21 to build the confidence that my
change works. If the change in 0.20 differs from that in 0.21 and
the trunk, it becomes harder for us to ensure the pipeline code
stability.
I would like to propose that we pull out HDFS-793 and HDFS-101 from
0.20.
Hairong
+1 to pull it out.
This part of the code is trick to get right and test.
