FilterList doesn't work right with filters (such as ColumPrefixFilter) which
use the SEEK_NEXT_USING_HINT

Key: HBASE-5104
URL: https://issues.apache.org/jira/browse/HBASE-5104
Project: HBase
Issue Type: Bug
Reporter: Kannan Muthukkaruppan
Assignee: Madhuwanti Vaidya
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).
