Surendra Singh Lilhore commented on HDFS-11695:
-----------------------------------------------

I feel {{FSDirAttrOp#unprotectedSatisfyStoragePolicy()}} should not throw the 
exception. It should remove inode from the candidate list which already have 
SPS xAttrs.
{code}
    if (inodeHasSatisfyXAttr(candidateNodes)) {
      throw new IOException(
          "Cannot request to call satisfy storage policy on path "
          + iip.getPath()
          + ", as this file/dir was already called for satisfying "
          + "storage policy.");
    }
{code}
[~umamaheswararao], [~rakeshr] Please give your opinion..

> [SPS]: Namenode failed to start while loading SPS xAttrs from the edits log.
