Varun Vasudev commented on YARN-4307:
-------------------------------------
My apologies for the delay Naga. Patch looks mostly good to me. Some more minor
nits -
1) rename getApplicationBlackListNodes to getBlackListedNodes
2) In RMAppAttemptBlock.java
{code}
+ String appBlacklistedNodes =
+ getNodeString(rmAppAttempt.getApplicationBlackListNodes());
+ String rmBlackListedNodes = getNodeString(
+ rmAppAttempt.getAMBlacklist().getBlacklistUpdates().getAdditions());
{code}
Add a comment explaining difference between the two.
3) In RMAppAttemptBlock.java
{code}
._("RM Blacklisted Nodes:", rmBlackListedNodes);
{code}
Change "RM Blacklisted Nodes" to "RM Blacklisted Nodes(for AM launches)"
4) In RMAppBlock.java
{code}
String appBlacklistedNodesCount = String.valueOf(nodes.size());
String rmBlacklistedNodesCount = String.valueOf(rmAppAttempt
.getAMBlacklist().getBlacklistUpdates().getAdditions().size());
{code}
Similar to (2) - add a comment explaining difference
5) In AppAttemptInfo
rename blacklistedNodesForAMByRM to rmBlacklistedNodesForAMLaunches
> Blacklisted nodes for AM container is not getting displayed in the Web UI
