Hi Manish:
Glad to receive your email because we are making efforts on HWI.
We have improved the orignal and added some features and putted it on
github:
https://github.com/anjuke/hwi
It's far from mature and standard, but it's improving and has already
deployed for our company to use.
After a
Maybe it's not.
But this exception happens when I create an *HiveHistoryViewer* instance,
in which case only reading, parsing file is invloved and it's not intended
to be shared between threads.
So the exception surprised me and I wonder why a static buffer was used
instead of a local buffer whic
Hi Jie:
As I know, hive history log is structured and class *HiveHistory* is used
to write and read hive history log.
*HiveHistoryViewer* serves as a listener to listen and store parsed log
data. It has two members:
HashMap *jobInfoMap*, which stores QueryInfo related
with hive query
and
HashM
It is likely an oversight. The Majority of hive code was not written to be
multi-threaded.

Hi all,
Can Hive implement the aggregation as a Map-only job? As we know the
data may be pre-partitioned via PARTITION-BY or CLUSTERED-BY, so we
don't need the reduce phase to repartition the data.
The Bucket Join seems to take advantage of the buckets for joins, so I
wonder if there is some simi
Hi Qiang,
Could you describe how HiveHistoryViewer is used? I'm also looking for
a tool to understand the Hive log.
Thanks,

Hi All,
We are exploring HWI to be used in PROD environment for adhoc queries etc.
Want to check out in the hive community that can somebody share there
experience while using the HWI in prod or any environment in terms of its
stability and performance.
Also evaluating to enhance to make it more u
Does Anybody have an idea about this?

Looks like this column is not even there in the 0.8/0.9 schema files . I have
no idea, how I have it in my schema . I just set a default 'false' value and I
m fine now.

So I read that JIRA, and also found this linked JIRA:

So I decided to try the * 1.0 work around.

from_utc_timestamp(starttime * 1.0, 'GMT') as
Brad is correct, there is a JIRA about this already:

Sorry for the inconvenience.

Try multiplying your values by 1000, then running the conversions. I bet they
expect milliseconds since the epoch instead of seconds.

One more test:
to_utc_timestamp(from_unixtime(value), 'CST') as to_from, provided the
proper timestamp for me, however, I still had to provide the timezone which
I should NOT have to do. I know that this data coming in is in epoch time,
therefore I should be able to create a timezone without knowi
Greetings all. I am getting frustrated with the documentation and lack of
intuitiveness in Hive relating to timestamps and was hoping I could post
here and get some clarification or other ideas.
I have a field that is a string, but is actually a 10 digit int
representation of epoch time, I am goin
they are in the src/service/if and src/metastore/if

I ended up increasing the counters limit to 130 which solved my issue.
Do you know of any good sources to learn how to decipher hive's EXPLAIN?
