Hi all (and happy New Year!)

Is it possible to build a perl Thrift client for HiveServer2 (from
Cloudera's 4.1.x) ?

I'm following the instructions found here:
http://stackoverflow.com/questions/5289164/perl-thrift-client-to-hive

Downloaded Hive from Cloudera's site, then i'm a bit lost: where do I find
these thrift files that I need to build the perl libs? I have the thrift
compiler working ok, but thats as far as I got.

Any help would be most welcome

Thanks!

D.Morel

they are in the src/service/if and src/metastore/if

Cool. But these would be files for HiveServer, not HiveServer2 which has a
different API, right? After finally generating the libs, it turns out they
work fine on the old-style hive server, but produce this in hiveserver2's

HiveServer2 now is CDH extension.

I think you can use find cmd to search the CDH src dir to find the .thrift
files.

So that would probably be generated using src/service/if/cli_service.thrift
instead of the older hive_service.thrift which i suppose is for hiveserver1.
Compiled it, still getting errors that seem transport-related

13/01/04 23:02:22 ERROR server.TThreadPoolServer: Error occurred during
processing of message.
java.lang.RuntimeException: org.apache.thrift.transport.TTransportException
at
org.apache.thrift.transport.TSaslServerTransport$Factory.getTransport(TSaslServerTransport.java:218)
...

This is a bit tedious...

Hi,

The Thrift IDL file for HiveServer2 is located here:

service/if/cli_service.thrift

Here's what you need to do in order to build the HiveServer2 Perl Thrift
client using the Hive tarball from CDH4.1.x:

# Set THRIFT_HOME to point to the installation directory of Thrift 0.9.0
% export THRIFT_HOME=<...>

# Verify that THRIFT_HOME is set properly
% $THRIFT_HOME/bin/thrift -version
Thrift Version 0.9.0

# Download and unpack the hive-0.9.0-cdh4.1.2 tarball
% wget http://archive.cloudera.com/cdh4/cdh/4/hive-0.9.0-cdh4.1.2.tar.gz
% tar -xvf hive-0.9.0-cdh4.1.2.tar.gz
% cd hive-0.9.0-cdh4.1.2/src

# Generate the Perl Thrift libraries
% ant thriftif -Dthrift.home=$THRIFT_HOME -Dthrift.args="-I $THRIFT_HOME
--gen perl"

The previous command will result in the generation of the HiveServer2 Perl
library here:

service/src/gen/thrift/gen-perl/TCLIService.pm

In order to use this library you can start with the code on stackoverflow
and modify
it to reference TCLIService instead of ThriftHiveClient. Also note that the
TCLIService
Thrift service exposes a different set of functions than the
ThriftHiveClient service.
I recommend looking at the comments in TCLIService.thrift in order to
understand
the proper workflow.

Thanks.

Carl
