-------------------------------------
Summary: OrcInputFormat.combineOrCreateETLStrategy() doesn't
combine if there are deltas
Key: HIVE-18110
URL: https://issues.apache.org/jira/browse/HIVE-18110
Project: Hive
Issue Type: Bug
Components: Transactions
Affects Versions: 3.0.0
Reporter: Eugene Koifman
this method has
{noformat}
if (!deltas.isEmpty() || combinedCtx == null) {
//why is this checking for deltas.isEmpty() - is this Acid 1.0 remnant?
return new ETLSplitStrategy(
context, fs, dir, files, readerTypes, isOriginal, deltas, covered,
ugi,
allowSyntheticFileIds, isDefaultFs);
} else
{noformat}
what is the purpose of checking deltas? (here with Acid 2.0 deltas is delete
deltas)
Is this some remnant of Acid 1.0?
