Keith Turner commented on ACCUMULO-776:
---------------------------------------
bq. I don't think anything is being changed in how things are being stored in
ZK.
No, I think your initial comments were correct. The date encoded string will
be stored in zookeeper, not a long. To be sure I ran a little test.
{code:java}
IteratorSetting is = new IteratorSetting(21, TimestampFilter.class);
TimestampFilter.setStart(is, System.currentTimeMillis(), false);
TimestampFilter.setEnd(is, System.currentTimeMillis() + 10000, false);
conn.tableOperations().attachIterator("foo", is);
Iterable<Entry<String,String>> propsIter =
conn.tableOperations().getProperties("foo");
for (Entry<String,String> entry : propsIter) {
if (entry.getKey().contains("Timestamp"))
System.out.println(entry);
}
{code}
This prints out the following :
{noformat}
table.iterator.majc.TimestampFilter.opt.start=20121106024224GMT
.
.
.
{noformat}
I think if I had applied the patch, a long would be stored in ZK instead.
> TimestampFilter should serialize start and end as longs in the IteratorSetting

>
> Although the TimestampFilter supports using longs to set the start or end
> timestamp, it formats them as strings using SimpleDateFormat when storing or
> retrieving them in the IteratorSetting.
> This results in exceptions when the timestamps being used aren't able to be
> formatted as _yyyyMMddHHmmssz_. For example, try
> {{setEnd(253402300800001,true)}}
> Instead, {{setStart()}} and {{setEnd()}} could just as easily use
> {{String.valueOf(long i)}} to store the values, and {{init()}} could retrieve
> them using {{Long.valueOf(String s)}}.
