Subject [jira] [Commented] (HBASE-4155) the problem in hbase thrift client when scan/get rows by timestamp
Date Tue, 02 Aug 2011 19:00:30 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4155?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13078365#comment-13078365

Ted Yu commented on HBASE-4155:

I suggest we keep the current behavior.
ThriftServer.HBaseHandler has reference to Configuration object. We can introduce a new config
option for setting exact timestamp instead of time range.

> I want to scan rows by specified timestamp. I use following hbase shell command :
> scan 'testcrawl',{TIMESTAMP=>1312268202071} 
> ROW                                         COLUMN+CELL                             
>  put1.com                                   column=crawl:data, timestamp=1312268202071,
>  put1.com                                   column=crawl:type, timestamp=1312268202071,
>  put1.com                                   column=links:outlinks, timestamp=1312268202071,
> As I expected, I can get the rows which timestamp is 1312268202071.
> But when I use thift client to do the same thing ,the return data is the rows which time
before specified timestamp ,  not the same as hbase shell.following is timestamp of return
> 1312179170000
> 1312268202059
> I look up the source in  hbase/src/main/java/org/apache/hadoop/hbase/thrift/ThriftServer.java,
it use following code to set time parameter .
> scan.setTimeRange(Long.MIN_VALUE, timestamp);
> This cause thrift client return rows before specified row ,not the rows timestamp specified.
> But in hbase client and avro client ´╝îit use following code to set time parameter.
> scan.setTimeStamp(timestamp);
> this will return rows timestamp specified.
> Is this a feature or a bug in thrift client ?
> if this is a feature, which method in thrift client can get the rows by specified timestamp?
