Hey Schubert,
Looking at the code on github, it looks like your rewritten shuffle is
in fact just a backport of the shuffle from MR2. I didn't look closely
- are there any distinguishing factors?
Also, the OOB heartbeat and adaptive heartbeat code seems to be the
same as what's in 1.0?

We recently upgraded to Hive-0.8.0 and noticed that all queries fail when
run as hive -e with the error ,

Hi Sam,
I tried running this against the hive-0.8.0 release tarball and did not
encounter any problems.
Is it possible that you have some old JARs or shell scripts hanging around
from a previous Hive install?

Sorry guys, I figured this out. We have a shell script that sets the env
variables and then calls the standard hive-0.8.0/bin/hive "$@" . The
problem was that the quotes around $@ were missing and the hive executable was
just getting the first word .
It was just my bad.
Thanks,
Sam
Hi: Todd
yes, the rewritten shuffle in actual a backport of the shuffle from MR2 .
We mainly add the following two features:
1) shuffle avoidance
2) work pool

Hi there,
I just want to have a simple hive interface with HWI. when I start it
with "hive --service hwi' it boots up but when I visit the index.jsp it
always complain 404.
This is what I am doing http://screencast.com/t/c5Qm8vnNAaI
any pointers?

1) it should be sort-avoidance.
2) work pool (like Tenzing)
Sorry ,the adaptive heartbeat code is not in this github code, we are
discussing it.

Hi, all:
I am a newbie to hive.
When I excute command (select count(*) from log where end_clock =
'2012-02-14_08'; ) in hive, it is OK.
While I excute command (select count(*) from log where end_clock >=
'2012-01-18_08' and end_clock <= '2012-02-14_08';) in hive, it report
the follo
11 matches
