Hi,
I got the following error while executing the "select count(1) from
tweettrend;"
Below are the exact log msg from the jobtracker Web Interface

if you look closely in first phase it executes your transform and in second
it does your sum operation

thanks. I used explain command and get the plan, but I am still confused.
The below is the description of two map-reduce stages:
it seems that in stage-1 the aggregation has already been done, why stage-2 has
aggregation again?

you can run explain extended (your query) to get more details

I am wondering how to determine the number of map-reduce for a hive query.
for example, the following query
select
sum(c1),
sum(c2),
k1
from
{
select transform(*) using 'mymapper' as c1, c2, k1
from t1
} a group by k1;
when i run this query, it takes two map-reduce, but I expect it to take
Thanks. There are at least 0.8.1 versions there. I still have not
found 0.9.0 or the new 0.10.0 anywhere.

There shouldn't be any problems with comments in Avro schemas. You
just need to make sure they're escaped properly. We did run into a
problem with schema.literal values longer than 4k (the size of the
backing mysql varchar field), so internally we just bump this value
for our Hive installs:

Hi folks,
Through samples here and there, I've seen tables definitions using RCFile
storage specifying a SERDE in somecase, and sometimes not.
ie : sometimes ROW FORMAT SERDE
'org.apache.hadoop.hive.serde2.columnar.ColumnarSerDe' STORED AS RCFILE
some other times, only : STORED AS RCFILE

Are you using Derby? Did you change directories? By default, Derby drops
the metastore_db in the current directory, but you can specify an absolute
path for it in the hive-site.xml config file, e.g.,:
javax.jdo.option.ConnectionURL
jdbc:derby:;databaseName=/path/to/metastore_db;create=true
The documentation links are broken on hive.apache.org for every
release newer than 0.7.1. Has the documentation been moved elsewhere?
Thanks,
lauren
