Eugene Koifman updated HIVE-18110:
----------------------------------
Description:
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?
Also see TestInputOutputFormat.testEtlCombinedStrategy
