Why is you cluster has "red" I am suspecting some disk space I am only guessing just run the host health check also
whats the parameter you had put in
<property> <name>yarn.scheduler.minimum-allocation-mb</name> <value>1024</value> </property>
in /hadoop/ conf.cloudera.yarn/map-redsite.xml it the following are set to 0, so I changed them to what is in /haddop/conf/map-redsite.xm
<property> <name>mapreduce.map.memory.mb</name> <value>1024</value> </property> <property> <name>mapreduce.map.cpu.vcores</name> <value>1</value> </property> <property> <name>mapreduce.reduce.memory.mb</name> <value>1024</value> </property>
I could not find the parameter
It is still at same point, no progress.
As pointed mostly like it will be the resource allocation on those parameter good that you found it in that thread .I was close to narrow it down . Guess what sometimes it could be some socket configuration on the OS too . The logs will clearly guide us to it .
