FW: hive/hbase integration with rebuilt handler

["Sun, Michael" <Sh...@searshc.com>]

Here is more info about the issues I have been facing.

 

1.       I rebuilt the hbase handler for both Hive 0.6.0 and 0.7.0 by
changing the appropriate settings below to generate the necessary
handler files;

2.       None of them was working and both made the hbase master "out of
memory" (see attached HMaster log) after firing following hiveSQL
command ( from hbase hive integration site
http://wiki.apache.org/hadoop/Hive/GettingStarted ):

 

CREATE TABLE hbase_table_1(key int, value string) STORED BY
'org.apache.hadoop.hive.hbase.HBaseStorageHandler' WITH SERDEPROPERTIES
("hbase.columns.mapping" = ":key,cf1:val") TBLPROPERTIES
("hbase.table.name" = "xyz");

 

The 'OutOfMemoryError' caused the hamster service unavailable, which is
the final message we saw from the hive log file.

 

My question:

1.       Is there any documented handler rebuild process anywhere to
integrate HBase 0.20.3/Zookeeper3.2.2/Hive0.6.0 (0.7.0)?

2.       What is the best approach to set up Hive environment for my
environment? Is it better to install CDH3 (from documentation, the
initial release of CDH3 compatible with hadoop0.20.2 and hbase0.20.3)
without patch and copy the hive directory to my prod environment?

 

Thanks

Hi, can any of you help to solve the error in the attachment when I
tried to integrate Hive and HBase?

 

Environment:

 

Hive version: 0.7.0

HBase version: 0.20.3

Hadoop version: 0.20.2

 

Steps I did to rebuild hiver-hbase-handler.jar:

 

1.       Checkout source from 
http://svn.apache.org/repos/asf/hive/branches/branch-0.7 (and
branch-0.6)

2.       Modify $checkout_root/build.properties to change the hadoop
version to 0.20.2

3.       Modify $ checkout _root/ivy/library.properties and
$root/ivy/ivysetting.xml to use my local jars in hbase/hadoop
installation

 

The rebuild process generated a new handler called
hive-hbase-handler-0.7.1-SNAPSHOT.jar.

 

Thanks
