Hive version is 1.2.1000.2.6.1.0-0129 ( HDP 2.6.1.0)
For now I have mitigated the problem by recreating the table. So, I don't
have the relevant ORC files right now.
Also, I am curious, how would "*hive.acid.key.index*" help in debugging
this problem ?
I was going through the source code and it seems the following line is the
problem:
/**
* Find the key range for bucket files.
* @param reader the reader
* @param options the options for reading with
* @throws IOException
*/
private void discoverKeyBounds(Reader reader,
Reader.Options options) throws IOException {
RecordIdentifier[] keyIndex = OrcRecordUpdater.parseKeyIndex(reader);
long offset = options.getOffset();
long maxOffset = options.getMaxOffset();
int firstStripe = 0;
int stripeCount = 0;
boolean isTail = true;
List<StripeInformation> stripes = reader.getStripes();
for(StripeInformation stripe: stripes) {
if (offset > stripe.getOffset()) {
firstStripe += 1;
} else if (maxOffset > stripe.getOffset()) {
stripeCount += 1;
} else {
isTail = false;
break;
}
}
if (firstStripe != 0) {
minKey = keyIndex[firstStripe - 1];
}
if (!isTail) {
maxKey = keyIndex[firstStripe + stripeCount - 1];
}
}
If this is still an open issue I would like to submit a patch to it.
Let me know how can I further debug this issue.
Thanks,
Aviral Agarwal
