It looks like only one user can access the Apache Derby DB. When I try to
have multiple jobs running on hive, the other jobs complain something like
this:
FAILED: Error in metadata: javax.jdo.JDOFatalDataStoreException: Failed to
start database '/hadoop/metastore_db', see the next exception for de
+1 for shorter release cycles.
Currently, is it time based or feature based ? If time based, whats
the timeline for 0.7 and if its feature based, which features are
"must" for 0.7 release?

Hello Hadoop fans,
The Bay Area Hadoop User Group meetups are a long hike for those of us who
come from San Francisco. I'd like to gauge interest in SF-centric Hadoop
gatherings.
In contrast to the presentation-based format of the usual HUG meetings, I'm
interested in holding events that are more
We branched 0.6 quite early and by that point we were only backporting blockers
for the release.
We're hoping we can make the 0.7 release cycle a lot shorter, and HIVE-1226
will be in there for sure.

We created the 0.6 branch several months before the actual 0.6
Thanks John. Just curious, I see the last commit for HIVE-1226 was almost a
month before the 0.6.0 release and I'm wondering why it didn't get into the
release.
Also, I agree theres a lot of duplicated code and will be happy to help out
in a refactoring effort.

HIVE-1226 (support for pushing filters down into storage handlers) is only in
trunk (not 0.6).
Separately: as a followup to HIVE-1434, it would be good to plan a refactoring
across the handlers for HBase/Hypertable/Cassandra since there is a lot of
duplicated code.

Hi,
I'm taking another pass over the Hypertable Hive storage handler and adding
a bit more functionality to it (including regexp filtering). I was also
planning to upgrade the Hive version it uses from something between 0.4 &
0.5 to 0.6. In this regard, my preference is to upgrade to 0.6 but I'm
Hi,
In MySQL to match '12684041234' to the longest prefix I would do
SELECT num_prefix
FROM nums
WHERE '12684041234' LIKE CONCAT(num_prefix, '%')
AND LENGTH(num_prefix) = (
SELECT MAX(LENGTH(num_prefix))
FROM nums
WHERE '12684041234' LIKE CONCAT(num_prefix, '%')
)
** Table nums has a column name
You can use a left outer join which works in all databases.
select a.value
from tablea a
left outer join tableb b on (b.value = a.value)
where b.value is null;
Databases are generally pretty good at doing joins so this usually performs
good.
