Rui Li updated HDFS-7866:
-------------------------
Attachment: HDFS-7866.13.patch
I realized that {{TestEditLog}} fails on trunk as well. So it's not related to
the patch here.
The v13 patch mainly addresses Walter's comments:
# Adds the JavaDoc.
# Moves LAYOUT_BIT_WIDTH and MAX_REDUNDANCY to {{HeaderFormat}}.
# Adds method {{getECPolicyID}} to {{HeaderFormat}} so that we don't have to
reuse {{getReplication}} to get the policy id. Currently we only have setter
for replication but not for EC policy, so don't need to take care of the setter.
# Updates {{TestErasureCodingPolicies#testReplication}} to make sure setting
replication on EC file doesn't mess up with the policy.
> Erasure coding: NameNode manages multiple erasure coding policies
