    Description

      Encountered an NPE when trying to use the HBase utility ExportSnapshot with Azure as the target.

      It turns out verifyAndConvertToStandardFormat is returning null when determining the hbaseRoot, and this is being added to the atomicRenameDirs set.

      java.lang.NullPointerException
