Thomas Graves commented on MAPREDUCE-4375:
------------------------------------------
Mostly looks good. A couple minor comments
- rename "sources" in ConfEntryInfo to be "source" to match whats in the actual
job.xml file.
- Add documentation to webservices docs - MapredAppMasterRest.apt.vm and
HistoryServerRest.apt.vm
- this wasn't introduced by this jira but I see when I look at the output from
webservices for a running app master the sources look like:
{
"sources" : [
"hdfs-default.xml",
"org.apache.hadoop.hdfs.DFSClient$DFSDataInputStream@135b95d"
],
"value" : "40000",
"name" : "dfs.namenode.checkpoint.txns"
},
I think the "org.apache.hadoop.hdfs.DFSClient$DFSDataInputStream@135b95d" is
supposed to be the hdfs location of the job.xml file it read. We can either
file a separate jira for that or fix it here if you want.
