Allen Wittenauer commented on HADOOP-9902:
------------------------------------------
bq. Found one more problem that RM and NM daemon logs are now inside *.out
file, instead of *.log file.
As mentioned in the release notes, YARN did a bunch of heinous stuff when it
came to log4j settings, counter to the rest of Hadoop, and to much frustration
with ops teams. This has been made consistent, so there is good chance you
were relying upon that behavior. It could be any number of things: NM and RM
_OPT settings, dependence upon the nodemanger/log4j.settings file or
resourcemanager/log4j.settings file, yarn-env.sh settings, etc. You can always
do 'bash -x yarn --daemon start resourcemanager'. The out file should contain
the java command line.
With the shipping *-env.sh files, you should see something similar to:
{code}
java -Dproc_resourcemanager -Djava.net.preferIPv4Stack=true
-Djava.security.krb5.realm= -Djava.security.krb5.kdc=
-Djava.security.krb5.conf=
-Dyarn.log.dir=/Users/aw/HADOOP/hadoop-3.0.0-SNAPSHOT/logs
-Dyarn.log.file=hadoop-aw-resourcemanager-aw-mbp-work.local.log
-Dyarn.home.dir=/Users/aw/HADOOP/hadoop-3.0.0-SNAPSHOT
-Dyarn.root.logger=INFO,RFA -Xmx1g
-Dhadoop.log.dir=/Users/aw/HADOOP/hadoop-3.0.0-SNAPSHOT/logs
-Dhadoop.log.file=hadoop-aw-resourcemanager-aw-mbp-work.local.log
-Dhadoop.home.dir=/Users/aw/HADOOP/hadoop-3.0.0-SNAPSHOT -Dhadoop.id.str=aw
-Dhadoop.root.logger=INFO,RFA -Dhadoop.policy.file=hadoop-policy.xml
-Dhadoop.security.logger=INFO,NullAppender
org.apache.hadoop.yarn.server.resourcemanager.ResourceManager
{code}
bq. Also yarn daemon log file name earlier was starting with "yarn", now it's
changed to "hadoop", not sure if this is an intentional change.
Intentional. This is to make YARN consistent with the rest of the system.
