Example 1 with ColumnVector

use of org.apache.orc.storage.ql.exec.vector.ColumnVector in project incubator-gobblin by apache.

the class GobblinBaseOrcWriter method removeRefOfColumnVectorChild.

Example 2 with ColumnVector

use of org.apache.orc.storage.ql.exec.vector.ColumnVector in project incubator-gobblin by apache.

the class GenericRecordToOrcValueWriter method write.

@Override
public void write(GenericRecord value, VectorizedRowBatch output) throws IOException {
    int row = output.size++;
    for (int c = 0; c < converters.length; ++c) {
        ColumnVector col = output.cols[c];

        }
    }
