I have an ImpalaRDD class:
public class ImpalaRDD<T> extends RDD<T> {
...
@Override
public Iterator<T> compute(Partition partition, TaskContext context) {
ImpalaPartitionIterator<T> iterator = new
ImpalaPartitionIterator<>(mapRow, (JdbcPartition) partition,
connectionProvider, partitioner, context);
TOperationHandle handle = getOperationHandle(iterator.statement);
return asScalaIterator(iterator);
}
...
}
Impala query operation handle can be used to track its progress. How to
share this handle to Spark driver?
