-----------------------------------

             Summary: BufferedDataBlockEncoder$OffheapDecodedExtendedCell.deepClone throws UnsupportedOperationException
                 Key: HBASE-26777
                 URL: https://issues.apache.org/jira/browse/HBASE-26777
             Project: HBase
          Issue Type: Bug
          Components: regionserver
    Affects Versions: 2.4.10
            Reporter: Istvan Toth


BufferedDataBlockEncoder$OffheapDecodedExtendedCell.deepClone throws an unsupportedException.

However, org.apache.hadoop.hbase.regionserver.HRegion.get(Get, boolean, long, long)

calls the method:
{code:java}
      // Copy EC to heap, then close the scanner.
      // This can be an EXPENSIVE call. It may make an extra copy from offheap to onheap buffers.
      // See more details in HBASE-26036.
      for (Cell cell : tmp) {
        results.add(cell instanceof ByteBufferExtendedCell ?
          ((ByteBufferExtendedCell) cell).deepClone(): cell);
      } {code}

According to the comment above, this is probably caused by HBASE-26036.
