URL: https://github.com/apache/incubator-druid/issues/7510#issuecomment-485418674
I've added some logs:
```
if (segmentsList.size() == userSuppliedSegmentsList.size()) {
Set<DataSegment> segmentsSet = new HashSet<>(segmentsList);
for (DataSegment userSegment : userSuppliedSegmentsList) {
if (!segmentsSet.contains(userSegment)) {
log.error("Segment %s is not present in %s",
userSegment,
segmentsSet.stream()
.map(DataSegment::toString)
.collect(Collectors.joining(","))
);
throw new IOException("user supplied segments list did not match with segments list obtained from db");
}
}
} else {
log.error("Different segment size: %d != %d", segmentsList.size(), userSuppliedSegmentsList.size());
throw new IOException("user supplied segments list did not match with segments list obtained from db");
}
```
and this is the error message:
```

In Aurora I've found `7` rows by running:
```
SELECT *
FROM druid_segments
WHERE
dataSource = "the-data-source"
AND used = true
AND start >= "2018-01-29T00:00:00.000Z"
AND end <= "2018-02-05T00:00:00.000Z";
```
which is the number specified by the aforementioned exception.
The S3 is also containing `7` files:
```
aws s3 ls --profile meru-prod s3://.../segments/the-data-source/2018-01-29T00:00:00.000Z_2018-02-05T00:00:00.000Z/2018-05-24T09:30:16.545Z/
PRE 0/
PRE 1/
PRE 2/
PRE 3/
PRE 4/
PRE 5/
PRE 6/
```
I don't know yet why `segmentsList` has `37` elements.
