Can someone explain how the Thriftserver finds the Hive metastore?
I am running with all non-default values and need to know how to connect to
Thrift so it finds Hive with the right metastore.
I am running Derby in server mode on a non-default port. And my metastore name
is non-default. And I
Sorry. I had an error in my message below. I start up Derby on the same port
that is specified in hive-site. So my derby start looks like:
nohup $DERBY_HOME/bin/startNetworkServer -h 0.0.0.0 -p
(not )
BTW, all the ports shown here are examples only.

I understand your concern with having a copy of the metastore code in Howl.
However, let's separate code from governance. The reason Howl has a copy
of Hive's metastore is not because we're proposing it for the

Hi,
The simplest of hive queries seem to be consuming 100% cpu. This is
with a small 4-node cluster. The machines are pretty beefy (16 cores
per machine, tons of RAM, 16 M+R maximum tasks configured, 1GB RAM for
mapred.child.java.opts, etc). A simple query like select count(1)

Hey,
If we do go ahead with pulling the metastore out of Hive, it might make
most sense for Howl to become its own TLP rather than a subproject.
Yes, I did not read the proposal closely enough. I think an end state as a
TLP makes more sense for Howl than as a Pig subproject. I'd really love
I am interested in some numbers around the lines of code changes (or
files of changes) which are in Howl but not in Hive?
Can anyone give some information here?
Thanks

There are none as of today. In the past, whenever we had to have
changes, we do it in a separate branch in Howl and once those get
committed to hive repo, we pull it over in our trunk and drop the
branch.

What I am referring to is metastore/ dir of hive, part of hive code
which howl cares about most. Other howl code is for additional
functionalities that Howl provides (none of which lives in metastore/
dir) they are in howl/ dir. There are few build file changes, but they
are trivial.

Actually I need to port some SQL queries to hive QL.
Lets say I have hive table t which has columns mobile_no, cookie, ip,
access_id.
Lets say I want to count unique users. My definition of of unique user = all

present) +
