GoldenGate實時投遞資料到大資料平臺（7）– Apache Hbase

Apache Hbase安裝及執行

安裝hbase1.4，確保在這之前hadoop是正常執行的。設定相應的環境變數，
export HADOOP_HOME=/u01/hadoop
export HBASE_HOME=/u01/hbase
export PATH=$PATH:$HADOOP_HOME/bin:$HBASE_HOME/bin

啟動hbase
./start-hbase.sh

確保hadoop, hbase能正常啟動，如有問題，可自行搜尋文件解決。
[oracle@ol66 bin]$ jps
11685 NodeManager
11157 SecondaryNameNode
10844 NameNode
11405 ResourceManager
13135 HMaster
13455 Jps
10959 DataNode

確保hbase在hadoop上正常執行
[oracle@ol66 u01]$ hdfs dfs -ls /

可以看到，系統中還沒有任何表。

OGG安裝及測試

配置OGG for bigdata的環境變數
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$JAVA_HOME/jre/lib/amd64/server

安裝ogg for bigdata 12.3版本軟體
進入ggsci
ggsci>create subdirs

退回到作業系統命令列，在OGG安裝目錄下執行如下命令，拷貝hbase示例投遞引數後進行修改
cp AdapterExamples/big-data/hbase/* dirprm/
在dirprm目錄下，編輯hbase.props檔案。
根據安裝的hbase的路徑，修改gg.classpath中 hbase lib的路徑；儲存退出。
hbase.props的完整內容如下：

gg.handlerlist=hbase

gg.handler.hbase.type=hbase
gg.handler.hbase.hBaseColumnFamilyName=cf
gg.handler.hbase.keyValueDelimiter=CDATA[=]
gg.handler.hbase.keyValuePairDelimiter=CDATA[,]
gg.handler.hbase.encoding=UTF-8
gg.handler.hbase.pkUpdateHandling=abend
gg.handler.hbase.nullValueRepresentation=CDATA[NULL]
gg.handler.hbase.authType=none
gg.handler.hbase.includeTokens=false

gg.handler.hbase.mode=tx

goldengate.userexit.timestamp=utc
goldengate.userexit.writers=javawriter
javawriter.stats.display=TRUE
javawriter.stats.full=TRUE

gg.log=log4j
gg.log.level=INFO
gg.report.time=30sec

gg.classpath=/u01/hbase/lib/*:/u01/hbase/conf/:

javawriter.bootoptions=-Xmx512m -Xms32m -Djava.class.path=ggjava/ggjava.jar

重新進入GGSCI，使用示例引數和示例佇列建立投遞程式。
GGSCI>add replicat rhbase, exttrail AdapterExamples/trail/tr
rhbase.prm的內容如下：

REPLICAT rhbase
-- Trail file for this example is located in "AdapterExamples/trail" directory
-- Command to add REPLICAT
-- add replicat rhbase, exttrail AdapterExamples/trail/tr
TARGETDB LIBFILE libggjava.so SET property=dirprm/hbase.props
REPORTCOUNT EVERY 1 MINUTES, RATE
GROUPTRANSOPS 10000
MAP QASOURCE.*, TARGET QASOURCE.*;

可以看到，OGG配置投遞到Hbase非常簡單，可以根據DB中表的主鍵欄位建立key，如果沒有PK欄位，則投遞時會報錯。以下是當前OGG版本支援的Hbase版本
