I have a row key of the form:
<name>--<zero-padded timestamp>
Using HBASE shell I want to find last 15 entries with the prefix .
scan 'mytable', {LIMIT => 15, ROWPREFIXFILTER => 'name' }
Gives me the first 15, but:
scan 'mytable', {LIMIT => 15, REVERSED => TRUE, ROWPREFIXFILTER => 'name'}
returns zero results...
What is the syntax for such a request?
Is it possible, or do I have to do something cheesy like use MAXINT-timestamp as my rowkey to manually reverse the key ordering?
I can execute your query command in HBase shell environment, and get the expected result. But couldn't get any result throw Java Client. My HBase version is 0.98.
There is a bug when use HBase client scan with reversed = true, see this jira issue hbase-client: scanner with reversed=true and small=true get no result
Yes, I reproduced this issue, and my result was the same.
The workaround I used was to change ROWPREFILTER
to STARTROW
and ENDROW
.
