it seems that hive.exec.reducers.bytes.per.reducer is still not big
enough: I added another 0, and now i only gets one file under each
partition.

Hi John
Number of mappers is equal to the number of splits generated. Following are the
factors that go into split generation
1) HDFS block size
2) Max split size
a split is cut when
1) the cumulative size of all adjacent stripes are greater than HDFS block size
2) the cumulative size of all adj
Hi,
I am using java reducer reading from a table, and then write to another one:
FROM (
FROM (
SELECT column1,...
FROM table1
WHERE ( partition > 6 and partition < 12 )
) A
MAP A.co
try "set hive.mapred.local.mem=7000" or add it to hive-site.xml instead of
modifying hive-env.sh
HADOOP_HEAPSIZE is not in use. Should fix documentation of it.
Thanks,

I have two clusters, but small dev clusters, and I loaded the same dataset
into both of them. The data size on disk is within 2000 Bytes. Both are
ORC, one is Hive 11 and one is Hive 12. One is allocating about 8 more
mappers to the exact same query. I am just curious what settings would
change
1. current implementation of hbase handler cannot pushdown filter with
'like' expression. You might rewrite the query some thing like "key >=
0010_0 AND key <= 0010_9"
2. Each of all tasks seemed to be scanning whole table (ie. 1000+ time),
which is fixed in HIVE-342
I have modified the title of the JIRA to properly reflect the issue faced -
Hive 0.11 & Hive 0.12 - derby.log and TempStatsStore are created when using
MySQL Metastore

Could you check the task log?
For stat gathering, hive uses derby by default. If the jdbc driver for
derby is not in auxlib, task cannot publish stats.

Hi,
I have checked my hive-site.xml ; it is fine ; hive metastore service is
running as well.
I have logged this - https://issues.apache.org/jira/browse/HIVE-6352

Hello,
see your hie-site.xml file, and check the database connexion( connexion
string) because in this file, that happend connexion to the metastore when
you start Hive.
Hope this helps you.

You can use explode function that is an udf in hive: like this
SELECT explode(ActivityDates) AS ActivityDates FROM myMapTable;
and think who to map the result whith rates ;)

Hi,
In oracle,DUMP returns a VARCHAR2 value containing the datatype code,
length in bytes, and internal representation of expr.
SELECT DUMP('abc', 1016)
FROM DUAL;
DUMP('ABC',1016)
--
Typ=96 Len=3 CharacterSet=WE8DEC: 61,62,63
Do we have any equivalen
