> PROBLEM: When enabling Namenode High Availability in Ambari, at the first
> step :"run "su -l hdfs -c 'hdfs dfsadmin -safemode enter'"
> run "su -l hdfs -c 'hdfs dfsadmin -saveNamespace'" "
> Ambari cannot detect the checkpoint has been created and would not allow user
> to go to next step.
> BUSINESS IMPACT: This bug is preventing customer to enable High
> Availability and customer is not able to avoid the single point of failure of
> their business.
> ACTUAL BEHAVIOR: The "Next Step" button is not available and user cannot go
> to next step.
> EXPECTED BEHAVIOR: After creating checkpoint, Ambari should detect the
> checkpoint and allow user to proceed to the next step.
> SUPPORT ANALYSIS: A possible workaround would be copy the link of checking
> checkpoint status, and access this link through a different browser.
> The customer use the following steps as a workaround:
> After leaving safe mode manually, then refreshing Ambari and starting wizard
> again, it say "Checkpoint created" even before entering safe mode again.
