Checking HBase installation… FAILED
When you try to install a Hadoop instance with the same name as a previous deleted one, you might get this error at the end of the installation process:
Checking HBase installation… FAILEDThen on the CMGUI/CMSH, warning events will come up like:
Service Hadoop-boston-hdfs-hbase-master died on hadoop1
Service Hadoop-boston-hdfs-hbase-master was restarted on hadoop1Solution
To get rid of these errors login on the head node as root, with all the Hadoop services running, and type:
module load zookeeper
zkCli.sh -server hadoop1 rmr /hbase-boston-hdfs
zkCli.sh -server hadoop2 rmr /hbase-boston-hdfs
zkCli.sh -server hadoop3 rmr /hbase-boston-hdfs
