    Description

      Recently some tests are failing and unable to loadFSEdits due to a failure in readCachePoolInfo.
      Here in below code
      FSImageSerialization.java

        }
          if ((flags & ~0x2F) != 0) {
            throw new IOException("Unknown flag in CachePoolInfo: " + flags);
          }
      

      When all values of CachePool variable set to true, flags value & ~0x2F turns out to non zero value. So, this condition failing due to the addition of 0x20 and changing &ing value from ~0x1F to ~0x2F.
      May be to fix this issue, we may can change multiply value to ~0x3F
