Examples with SettableTreeReader org.apache.hadoop.hive.ql.io.orc.encoded.EncodedTreeReaderFactory.SettableTreeReader used on opensource projects

Example 1 with SettableTreeReader

use of org.apache.hadoop.hive.ql.io.orc.encoded.EncodedTreeReaderFactory.SettableTreeReader in project hive by apache.

the class OrcEncodedDataConsumer method repositionInStreams.

private void repositionInStreams(TreeReaderFactory.TreeReader[] columnReaders, EncodedColumnBatch<OrcBatchKey> batch, boolean sameStripe, ConsumerStripeMetadata stripeMetadata) throws IOException {
    PositionProvider[] pps = createPositionProviders(columnReaders, batch.getBatchKey(), stripeMetadata);
    if (pps == null)
        return;
    for (int i = 0; i < columnReaders.length; i++) {
        TreeReader reader = columnReaders[i];
        // Note: we assume this never happens for SerDe reader - the batch would never have vectors.
        // That is always true now; but it wasn't some day, the below would throw in getColumnData.
        ((SettableTreeReader) reader).setBuffers(batch, sameStripe);
        // SettableTreeReader so that we can avoid this check.
        if (reader instanceof EncodedTreeReaderFactory.TimestampStreamReader && !sameStripe) {
            ((EncodedTreeReaderFactory.TimestampStreamReader) reader).updateTimezone(stripeMetadata.getWriterTimezone());
        }
        reader.seek(pps);
    }
