1.安装phoenix
在界面上设置Phoenix的parcel包:
http://52.11.56.155:7180/cmf/settings?groupKey=config.scm.parcel.display_group&groupParent=
添加一个Remote Parcel Repository URLs url:http://archive.cloudera.com/cloudera-labs/phoenix/parcels/1.0/
CM会自动发现新的parcel，然后点击Download,Distribute and Active。重启集群
2.进入到某台服务器上，查看phoenix的安装路径
[root@ip-172-31-25-243 ~]# cd /opt/cloudera/parcels/CLABS_PHOENIX [root@ip-172-31-25-243 phoenix]# ls bin dev examples lib phoenix-4.3.0-clabs-phoenix-1.0.0-client.jar phoenix-4.3.0-clabs-phoenix-1.0.0-server.jar phoenix-4.3.0-clabs-phoenix-1.0.0-server-without-antlr.jar
bin目录下为可执行文件，examples目录下为一些样例
3.导入CSV格式的表
CSV文件为/root/ceb/cis_cust_imp_info.csv,内容如下：
20131131,100010001001,BR01,2000.01 20131131,100010001002,BR01,2000.02 20131131,100010001003,BR02,2000.03
定义一个表结构的文件/root/ceb/cis_cust_imp_info.sql，内容如下，
CREATE TABLE IF NOT EXISTS cis_cust_imp_info( statistics_dt varchar(50), cust_id varchar(50), open_org_id varchar(50), assert9_bal decimal(18,2), CONSTRAINT pk PRIMARY KEY (statistics_dt, cust_id) );
注意最后的分号是必须的。
运行命令，导入CSV
[root@ip-172-31-25-243 phoenix]# bin/psql.py 172.31.25.244 /root/ceb/cis_cust_imp_info.sql /root/ceb/cis_cust_imp_info.csv SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". SLF4J: Defaulting to no-operation (NOP) logger implementation SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details. 15/09/04 10:26:59 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable 15/09/04 10:27:00 WARN impl.MetricsConfig: Cannot locate configuration: tried hadoop-metrics2-phoenix.properties,hadoop-metrics2.properties no rows upserted Time: 0.259 sec(s) csv columns from database. CSV Upsert complete. 3 rows upserted Time: 0.067 sec(s)
在hbase shell中进行验证：
hbase(main):001:0> list TABLE CIS_CUST_IMP_INFO SYSTEM.CATALOG SYSTEM.SEQUENCE SYSTEM.STATS 4 row(s) in 0.2650 seconds => ["CIS_CUST_IMP_INFO", "SYSTEM.CATALOG", "SYSTEM.SEQUENCE", "SYSTEM.STATS"] hbase(main):002:0> scan 'CIS_CUST_IMP_INFO' ROW COLUMN+CELL 20131131x00100010001001 column=0:ASSERT9_BAL, timestamp=1441362422661, value=xC2x15x01x02 20131131x00100010001001 column=0:OPEN_ORG_ID, timestamp=1441362422661, value=BR01 20131131x00100010001001 column=0:_0, timestamp=1441362422661, value= 20131131x00100010001002 column=0:ASSERT9_BAL, timestamp=1441362422661, value=xC2x15x01x03 20131131x00100010001002 column=0:OPEN_ORG_ID, timestamp=1441362422661, value=BR01 20131131x00100010001002 column=0:_0, timestamp=1441362422661, value= 20131131x00100010001003 column=0:ASSERT9_BAL, timestamp=1441362422661, value=xC2x15x01x04 20131131x00100010001003 column=0:OPEN_ORG_ID, timestamp=1441362422661, value=BR02 20131131x00100010001003 column=0:_0, timestamp=1441362422661, value= 3 row(s) in 0.1840 seconds
4.以MR的方式导入大量CSV文件
[root@ip-172-31-25-243 phoenix]# hadoop jar phoenix-4.3.0-clabs-phoenix-1.0.0-client.jar org.apache.phoenix.mapreduce.CsvBulkLoadTool --table cis_cust_imp_info --input /root/ceb/cis_cust_imp_info.csv --zookeeper 172.31.25.244
发生错误：

网上搜索，发现是由于HBASE的一个bug，解决方法是:
[root@ip-172-31-25-243 phoenix]# cd /opt/cloudera/parcels/CDH/lib/hadoop ln -s /opt/cloudera/parcels/CDH-5.4.5-1.cdh5.4.5.p0.7/lib/hbase/lib/hbase-protocol-1.0.0-cdh5.4.5.jar hbase-protocol-1.0.0-cdh5.4.5.jar
重新运行导入命令，发现如下错误:
15/09/04 11:04:43 WARN security.UserGroupInformation: PriviledgedActionException as:root (auth:SIMPLE) cause:org.apache.hadoop.security.AccessControlException: Permission denied: user=root, access=WRITE, inode="/user":hdfs:supergroup:drwxr-xr-x at org.apache.hadoop.hdfs.server.namenode.DefaultAuthorizationProvider.checkFsPermission(DefaultAuthorizationProvider.java:257) at org.apache.hadoop.hdfs.server.namenode.DefaultAuthorizationProvider.check(DefaultAuthorizationProvider.java:238)
原因是/user目录权限问题，用hdfs用户重新跑一遍，发生错误。用chmod 修改/user为777
sudo -u hdfs hdfs dfs -chmod 777 /user
sudo -u hdfs hadoop jar phoenix-4.3.0-clabs-phoenix-1.0.0-client.jar org.apache.phoenix.mapreduce.CsvBulkLoadTool --table cis_cust_imp_info --input /root/ceb/cis_cust_imp_info.csv --zookeeper 172.31.25.244
15/09/04 11:06:05 ERROR mapreduce.CsvBulkLoadTool: Import job on table=CIS_CUST_IMP_INFO failed due to exception:org.apache.hadoop.mapreduce.lib.input.InvalidInputException: Input path does not exist: hdfs://ip-172-31-25-243.us-west-2.compute.internal:8020/root/ceb/cis_cust_imp_info.csv
15/09/04 11:06:05 INFO client.ConnectionManager$HConnectionImplementation: Closing zookeeper sessionid=0x14f97b7df1400a4
原来用MR模式跑，文件需要放到HDFS上
这时MR运行可以顺利完成，HFile顺利生产，但是在loadIncremental环境卡住了。原因在于load到hbase中的表属于hbase:hbase，但生产的HFile文件属于当前用户和组。所以以hbase用户运行
sudo -u hbase hadoop jar phoenix-4.3.0-clabs-phoenix-1.0.0-client.jar org.apache.phoenix.mapreduce.CsvBulkLoadTool --table cis_cust_imp_info --input /root/ceb/cis_cust_imp_info.csv --zookeeper 172.31.25.244
顺利搞定！
