> How to reproduce?
> Configure StringTreeReader which contains StringDirectTreeReader as
> TreeReader (DIRECT or DIRECT_V2 column encoding)
> batchSize = 1026;
> invoke method nextVector(ColumnVector previousVector,boolean[] isNull, final
> int batchSize)
> scratchlcv is LongColumnVector with long[] vector (length 1024)
> which execute BytesColumnVectorUtil.readOrcByteArrays(stream, lengths,
> scratchlcv,result, batchSize);
> as result in method commonReadByteArrays(stream, lengths, scratchlcv,
> result, (int) batchSize) we received
> ArrayIndexOutOfBoundsException.
> If we use StringDictionaryTreeReader, then there is no exception, as we have
> a verification scratchlcv.ensureSize((int) batchSize, false) before
> reader.nextVector(scratchlcv, scratchlcv.vector, batchSize);
> These changes were made for Hive 2.1.0 by corresponding commit
> https://github.com/apache/hive/commit/0ac424f0a17b341efe299da167791112e4a953e9#diff-a1cec556fb2db4b69a1a4127a6908177R1467
> for task https://issues.apache.org/jira/browse/HIVE-12159 by Owen O'Malley
> How to fix?
> add only one line :
> scratchlcv.ensureSize((int) batchSize, false) ;
> in method
> org.apache.orc.impl.TreeReaderFactory#BytesColumnVectorUtil#commonReadByteArrays(InStream
> stream, IntegerReader lengths,
> LongColumnVector scratchlcv,
> BytesColumnVector result, final int batchSize) before invocation
> lengths.nextVector(scratchlcv, scratchlcv.vector, batchSize);
