I am installing cloudera manager, however when I check the memory with command hdfs dfsadmin -report, i can see that i have 1 dead datanode. How can I bring it lo live again?
is your Cloudera installed on Linux or Windows
Log on to the dead datanode and go /var/log/hadoop-hdfs/ You should see your log files there. You can print it using "cat"
Windows: Check your hdfs config and see whare are your log installed.
