Sergey Shelukhin commented on HIVE-20305:
-----------------------------------------
[~ekoifman] I see that canUseLlapIo in OrcSplit guards against this:
{code}
if (isOriginal) {
if (!isAcidRead && !hasDelta) {
// Original scan only
return true;
{code}
I actually wonder if this needs to be fixed. This method should allow the scan
and somehow propagate the original flag for the split (at least if there are no
deltas).

> Key: HIVE-20305
> URL: https://issues.apache.org/jira/browse/HIVE-20305
> Project: Hive
> Issue Type: Bug
> Components: llap, Transactions
> Affects Versions: 3.0.0
> Reporter: Eugene Koifman
> Priority: Major
>
> LlapRecordReader uses OrcInputFormat.getRootColumn(false) so it seems to
> assume that
> if {{AcidUtils.isFullAcidScan(jobConf)}} then the underlying file has acid
> meta columns in it. That is not true, for data added via Load Data, Add
> Partition or converting flat table to full CRUD acid via Alter Table (by
> setting transactional=true tbl property).
