> Bug in HoodieCombineRealtimeRecordReader returns wrong results

> Key: HUDI-1539
> URL: https://issues.apache.org/jira/browse/HUDI-1539
> Project: Apache Hudi
> Issue Type: Bug
> Affects Versions: 0.8.0
> Reporter: satish
> Assignee: satish

> in a rt table
> the hive query has predicate push down
> there are no less than 3 splits (thus no less than 3 recordReaders in
> HoodieCombineRealtimeRecordReader), and the records satisfy the predicate are
> in the split which is in a relatively back position of the List
> 2 recordReaders in succession with this.currentRecordReader.next(key, value)
> returns false, as the predicate push down has filtered the baseFile.
> In step 4, it leads to HoodieCombineRealtimeRecordReader::next(NullWritable
> key, ArrayWritable value) return false and the reader will stop read next.
> So, records which satisfy the predicate are in the remanined recordReaders
> but can not be read.
