Hi,
I am runing Hive and Hbase on the same Amazon EC2 cluster, where Hbase
is in a pseudo-distributed mode.
After integrating HBase in Hive, I find that it takes a long time when
runing a "insert overwrite" query from hive in order to load data into a
related HBase table.
In fact, the size of data is about 1.3Gb. I dont think it's normal.
Maybe there are something wrong with my configuration.
Here are some queries:
CREATE TABLE hbase_table (
material_id int,
new_id_client int,
last_purchase_date int)
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
WITH SERDEPROPERTIES ("hbase.columns.mapping" =
":key,cf1:idclt,cf1:dt_last_purchase")
TBLPROPERTIES("hbase.table.name" = "test");
insert OVERWRITE TABLE t_LIGNES_DERN_VENTES
select * from test; -- takes a long time (about 8 hours)
Here are some configurations files for my cluster :
# cat hive/conf/hive-site.xml
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>hbase.zookeeper.quorum</name>
<value>ip-10-159-41-177.ec2.internal</value>
</property>
<property>
<name>hive.aux.jars.path</name>

</property>
<property>

</configuration>
Any help is highly appreciated!
Thank you.
