> Thanks Jiakai Liu for reporting this issue and doing the initial investigation. Email from Jiakai below:
> Assuming that we have an index column family with the following entries:
> "tag0:001:thread1"
> ...
> "tag1:001:thread1"
> "tag1:002:thread2"
> ...
> "tag1:010:thread10"
> ...
> "tag2:001:thread1"
> "tag2:005:thread5"
> ...
> To get threads with "tag1" in range [5, 10), I tried the following code:
>     ColumnPrefixFilter filter1 = new ColumnPrefixFilter(Bytes.toBytes("tag1"));
>     ColumnPaginationFilter filter2 = new ColumnPaginationFilter(5 /* limit */, 5 /* offset */);
>     FilterList filters = new FilterList(Operator.MUST_PASS_ALL);
>     filters.addFilter(filter1);
>     filters.addFilter(filter2);
>     Get get = new Get(USER);
>     get.addFamily(COLUMN_FAMILY);
>     get.setMaxVersions(1);
>     get.setFilter(filters);
> Somehow it didn't work as expected. It returned the entries as if the filter1 were not set.
> Turns out the ColumnPrefixFilter returns SEEK_NEXT_USING_HINT in some cases. The FilterList filter does not handle this return code properly (treat it as INCLUDE).
