Hello all, Need your help in fixing this issue.
I can see that the dashboard opens but does not show any jobs Can anyone please help us to troubleshoot this issue.
Following I can see in mysql - Server version: 5.7.21-log MySQL Community Server (GPL)
We are using cloudera and the property yarn.resourcemanager.webapp.addres is already in place in CM.
and we have also configured HADOOP_HOME as parameter before triggering Dr elephant. Following are the parameters - export HADOOP_HOME=/opt/cloudera/parcels/CDH/lib/hadoop
export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop
export PATH=$HADOOP_HOME/bin:$PATH Now, we dont change anything on name node / data node and do all changes via CM, so how do i fix the below issue.
