Hi,
I am using ambari 2.7 blueprint to install HDP3.0. After installing, the
active namenode cannot start due to error:
2018-07-30 04:41:03,839 WARN namenode.FSNamesystem
(FSNamesystem.java:loadFromDisk(716)) - Encountered exception loading

java.io.IOException: NameNode is not formatted.

By running "sudo -u hdfs hdfs namenode -format" mentioned in
https://community.cloudera.com/t5/Cloudera-Manager-Installation/Got-error-java-io-IOException-NameNode-is-not-formatted-but/td-p/56814,
I am able to start namenode. However, for HDP installation automation, I
should not have run this command manually.
Any idea why ambari failed to format namenode in the first place? Thanks.
