problems of searching data using java thrift api

[Frank Zhou]

when I use java apis to search data from hypertable , there are some problem:

I set ColumnPredicate and set columns like this:

// set column predicates

ColumnPredicate cp = new ColumnPredicate();

cp.setColumn_family("age");

cp.setOperation(ColumnPredicateOperation.PREFIX_MATCH);

cp.setValue("3");

scan_spec.addToColumn_predicates(cp);

//set columns

scan_spec.addToColumns("name");

scan_spec.addToColumns("age");

but the result only contain one column 'age':

rowkey: 01

family: age

qualifier:

value: 30

The table is like this:

create table user (name, age, index age);

data is like this:

01      name    zhou

01      name:nakename   san

01      age     30

but when using C++ apis, it can return column "age" and "name".

Is there any bugs about the java thrift apis?

How to make java return all columns I need?

Hi Frank,

this could be a bug in the ThriftBroker. I filed issue 974 and will have a look. I'll try to fix it for the next release.

From where u get the hypertable.jar ?? I downloaded hypertable zip file from http://www.hypertable.com. Then I extracted that .zip file. In that i searched a lot, I dint get the hypertable<current version>.jar file.In their site, They just given add  hypertable<current version>.jar file to the classpath. There I'm confused. Please tell me step by step to set classpath to hypertable<current version>.jar file. 

Thanks.

Just unpack the zip file and you should find the jar files in the lib/java subdirectory.

I'm damn sure, There is no hypertable<version>.jar file. I downloaded all versions of hypertable .zip file from 0.9.7.0 to 0.9.7.8. I searched a lot, I din't get. If that hypertable<version>.jar file really there, then at least send the .zip file to ramakri...@dioxe.com and plz mention where is the hypertable<version>.jar file in that .zip after extracted.I'm using windows 7. I got only jars whose path is "C:\Users\Ozoneadmin\Desktop\New folder\hypertable-0.9.7.8\lib\<list of .jar files(but no hypertable.jar file)>". Even I gt libthrift_0.8.0 dependency jar and other jars like log4j,commons etc., 

[Christoph Rupp]

I just downloaded 0.9.7.8 and found the file in here:
/opt/hypertable/0.9.7.8/lib/java/cdh3/

and in here - depending on the CDH version that you use:
/opt/hypertable/0.9.7.8/lib/java/cdh4

If you would have properly installed hypertable and configured a CDH version then you would also have found the file in /opt/hypertable/0.9.7.8/lib/java.

Yup, I properly Installed hypertable.exe from http://ht4w.softdev.ch/index.php/downloads. After I install c->prgrms files->hypertable I can see all 7 .exe files, 1 CHANGES file, 1 license.txt file and 1 conf folder inside it contains 2 .xml files. I dint get capistrano capfile. How Do I install and configure that .gem file? That is a serialized object I think so. CDH means that only nah? 

[Ramakrishna Kc]

Can you plz make video of installation and configuration with a basic operations like insert,update,delete and retrieve data from hyper-table in windows from beginning and send/upload it?  Plz send me a link after if you done video and upload.

If you do video, it'll be more useful for most of the people including me also. 

Thanks.

[Christoph Rupp]

I certainly won't do that.

There's so much high quality documentation online, if you would just invest a few minutes of time and skim through it then you would know where to start looking.

http://hypertable.com/documentation

Start with "Overview" and "Architecture", then continue with "Developer Guide" -> "HQL Tutorial".

And maybe the Windows package/webpage has additional documentation that you can read.
