Hi Good People,
I am totally stumped on this one. Wondered if a "perl" bindings chap on
this list might be able to help me.
I generated the ThrftHive.pm class as follows (see below) from my download
area. I've tested some basic examples of querying - and it works well.
The one thing that i can't get to work, though, is a call to
"$client->getSchema()" in order to ascertain the schema of a result set.
* this built ThriftHIve.pm
$ thrift -r \
-I $HOME/downloads/hive-0.9.0/src/ql \
-I $HOME/downloads/hive-0.9.0/src \
-I $HOME/downloads/thrift-0.8.0 \
\
-gen perl \
\
$HOME/downloads/hive-0.9.0/src/service/if/hive_service.thrift
* in hive_service.thrift here are the relevant lines (that i can tell)
#the includes
include "contrib/fb303/if/fb303.thrift"
include "metastore/if/hive_metastore.thrift"
include "ql/if/queryplan.thrift"
namespace java org.apache.hadoop.hive.service
namespace cpp Apache.Hadoop.Hive
<snip>
#the getSchema() reference
service ThriftHive extends hive_metastore.ThriftHiveMetastore {
<snip>
# Get a schema object with fields represented with native Hive types
hive_metastore.Schema getSchema() throws(1:HiveServerException ex)
* the relevant line in ThriftHive.pm that throws an undefined method call:
Undefined subroutine &ThriftHive_getSchema_result::Schema called at
/home/spragues/downloads/thrift-0.8.0/gen-perl/ThriftHive.pm line 672.
$self->{success} = new Schema();
$xfer += $self->{success}->read($input);
Where 'o where is this "Schema" class supposed to be? Any pointers, clues,
suggestions, bread crumbs most welcome!
Thanks
Stephen
