      Description

      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.
