Nigel Daley updated HADOOP-3251:
--------------------------------
Component/s: (was: mapred)
dfs
Description:
When a job is run, a WARN message is given on the command line. This does not
affect the cluster functionality, but is bad user experience. Hence, marking
this a blocker for 0.17.0
The message is:
08/04/14 20:53:46 WARN fs.FileSystem: "namenode:59440" is a deprecated
filesystem name. Use "hdfs://namenode:59440/" instead.
was:
When a cluster is allocated thru HoD, dfs commands throw a WARN message on the
command line. This does not affect the cluster functionality, but is bad user
experience. Hence, marking this a blocker for 0.17.0
The message is:
08/04/14 20:53:46 WARN fs.FileSystem: "namenode:59440" is a deprecated
filesystem name. Use "hdfs://namenode:59440/" instead.
The entries in HoD generated hadoop-site.xml should be changed to use
*hdfs://namenode*, instead of just *namenode*

Summary: WARN message on command line when a hadoop jar command is
executed (was: hod generated hadoop-site.xml causes hadoop to throw a WARM
message on command line when a hadoop command is executed)
This WARN message started to appear after the fix for HADOOP-1967. Assigning
to dfs for further investigation. See Amar's 1st comment. Thinking more about
this, solution (1) from Amar (Replace all the occurrences of
FileSystem.getName() with FileSystem.getUri().toString()) seems like the right
approach, but seems like too big a change for 0.17 this late in the release.
How about removing the WARN message from FileSystem for 0.17 and then fix this
issue properly for 0.18 (putting the WARN message back in) and then remove the
deprecated method in 0.19. Thoughts?
