Original Estimate: 1m

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, value=htmlput1/html
put1.com column=crawl:type,
timestamp=1312268202071, value=html
put1.com column=links:outlinks,
timestamp=1312268202071, value=www.163.com;www.sina.com
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 data:
131217917
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 ，it 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?

@zezhou:
Except for getVerTs(), all the other getXX() methods should be changed.
Your patch was a diff which cannot be applied to Apache repository.
Please generate patch using subversion or git.

+1 on patch version 2.
Minor comment, the following line is called twice in scannerOpenWithStopTs():
{code}
scan.setTimeStamp(timestamp);
{code}
But this was due to double call in the current class.

Looks like certain test depends on the current behavior of getRowTs():

We need to decide whether modifying the test accordingly is the way to go.

I dug back in the commits to see when this was introduced, and it seems that
this was done as part of the uber refactoring done in HBASE-1304 two years ago.
The behavior does seem broken tho, it should set the timestamp and not a time
range (that would be another method). How it works right seems
counter-intuitive.
So I would be +1 on fixing it, but the main issue would be that some users
might already rely on the current behavior (I know that we don't here).
Others using Thrift want to comment?

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.

Yeah that's an option... and then we deprecate it for the next major version?
That means we also have to print out in bold letters when people that function
that it's going to be deprecated... although you might want to print that out
only once. In any case we need to find a good way to communicate our intent to
the users.
But now looking the idl I'm starting to think we should just change the
behavior:
{noformat}
/**
* Get the specified number of versions for the specified table,
* row, and column. Only versions less than or equal to the specified
* timestamp will be returned.
*
* @return list of cells for specified row/column
*/
listTCell getVerTs(
...
/**
* Get all the data for the specified table and row at the specified
* timestamp. Returns an empty list if the row does not exist.
*
* @return TRowResult containing the row and map of columns to TCells
*/
listTRowResult getRowTs(
...
/**
* Get a scanner on the current table starting at the specified row and
* ending at the last row in the table. Return the specified columns.
* Only values with the specified timestamp are returned.
*
* @return scanner id to be used with other scanner procedures
*/
ScannerID scannerOpenTs(
{noformat}
getVerTs has the right documentation, but not scannerOpenTs and getRowTs since
they also use the TimeRange (but the behavior we want is documented).

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 ，it 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?

We should correct the implementation of scannerOpenTs and getRowTs.
the problem in hbase thrift client when scan/get rows by timestamp

Key: HBASE-4155
URL: https://issues.apache.org/jira/browse/HBASE-4155
Project: HBase
Issue Type: Bug
Components: thrift
Affects Versions: 0.90.0
Reporter: zezhou
Original Estimate: 1m
Remaining Estimate: 1m
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, value=htmlput1/html
put1.com column=crawl:type,
timestamp=1312268202071, value=html
put1.com column=links:outlinks,
timestamp=1312268202071, value=www.163.com;www.sina.com
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 data:
131217917
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 ，it 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?
