[jira] [Updated] (HIVE-19137) orcfiledump doesn't print hive.acid.version value

     [ https://issues.apache.org/jira/browse/HIVE-19137?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Eugene Koifman updated HIVE-19137:
----------------------------------
    Description: 
HIVE-18659 added hive.acid.version in the file footer.  
orcfiledump prints something like 
{noformat}
User Metadata:
  hive.acid.key.index=1,536870912,1;
  hive.acid.stats=2,0,0
  hive.acid.version=
{noformat}

probably because
{noformat}
    public static void setAcidVersionInDataFile(Writer writer) {
      //so that we know which version wrote the file
      ByteBuffer bf = ByteBuffer.allocate(4).putInt(ORC_ACID_VERSION);
      bf.rewind(); //don't ask - some ByteBuffer weridness. w/o this, empty buffer is written
      writer.addUserMetadata(ACID_VERSION_KEY, bf);
    }
{noformat}

use 
{{UTF8.encode())}} instead
