Subject: YARN NM containers were killed
To: [EMAIL PROTECTED]
i've tested the hadoop-mapreduce-examples-2.0.0-cdh4.1.2.jar on my hadoop
environment
(   1 RM - Hadoop01 and 3 NM --Hadoop02,Hadoop03,Hadoop04
  OS:CDH4.1.2 rhel5.5):
./bin/hadoop jar
share/hadoop/mapreduce/hadoop-mapreduce-examples-2.0.0-cdh4.1.2.jar
 wordcount 1/input output

when i checked the log .i was confused by the plz:
my hadoop creates 2 containers in Hadoop02,1 container in Hadoop03 ,however
0 container Hadoop04.

the result of the containers processing:

Hadoop02:
* container_1359422495723_0001_01_000001
(its state changes as follows:NEW --> LOCALIZING --> LOCALIZED --> RUNNING
--> KILLING --> EXITED_WITH_SUCCESS)

      the log indates that:
NodeStatusUpdaterImpl: Sending out status for container: container_id {,
app_attempt_id {, application_id {, id: 1, cluster_timestamp:
1359422495723, }, attemptId: 1, }, id: 1, }, state: C_RUNNING, diagnostics:

Hadoop03:
        * container_1359422495723_0001_01_000002

CONTAINERID=container_1359422495723_0001_01_000002

My questions:
        1. Why  were 2 containers created in Hadoop02,however Hadoop04 got
nothing.is it normal ?
2. What is the principle that guides containers to be created.
 3. Why were the two containers (the container_*_000003 and the
container_*_000002)  killed, while the container_*_000001 succeeded.
   is it normal?
logs of Hadoop01 as follows:
