hive如何整合phoenix

這篇文章主要為大家展示了“hive如何整合phoenix”，內容簡而易懂，條理清晰，希望能夠幫助大家解決疑惑，下面讓小編帶領大家一起研究并學習一下“hive如何整合phoenix”這篇文章吧。

首先需要phoenix整合hbase

hive整合hbase，此處參照之前的筆記

將phoenix{core,queryserver,4.8.0-HBase-0.98,hive}拷貝到$hive/lib/

根據官網要求修改配置文件

> vim conf/hive-env.sh

> vim conf/hive-site.xml

啟動：

> hive -hiveconf phoenix.zookeeper.quorum=hadoop01:2181

創建內部表

create table phoenix_table (

s1 string,

i1 int,

f1 float,

d1 double

)

STORED BY 'org.apache.phoenix.hive.PhoenixStorageHandler'

TBLPROPERTIES (

"phoenix.table.name" = "phoenix_table",

"phoenix.zookeeper.quorum" = "hadoop01",

"phoenix.zookeeper.znode.parent" = "/hbase",

"phoenix.zookeeper.client.port" = "2181",

"phoenix.rowkeys" = "s1, i1",

"phoenix.column.mapping" = "s1:s1, i1:i1, f1:f1, d1:d1",

"phoenix.table.options" = "SALT_BUCKETS=10, DATA_BLOCK_ENCODING='DIFF'"

);

創建成功。查詢phoenix和hbase中都有相應的表生成：phoenix

hbase：

屬性

1. phoenix.table.name

• 
  

• phoenix指定表名

• 默認值:hive一樣的表

1. phoenix.zookeeper.quorum

• 
  

• 指定ZK地址

• 默認值:localhost

1. phoenix.zookeeper.znode.parent

• 
  

• 指定HBase在ZK的目錄

• 默認值:/ hbase

1. phoenix.zookeeper.client.port

• 
  

• 指定ZK端口

• 默認值:2181

1. phoenix.rowkeys

• 
  

• 指定phoenix的rowkey，即hbase的rowkey

• 要求

1. phoenix.column.mapping

• 
  

• hive與phoenix之間的列映射。

插入數據

使用hive測試表pokes導入數據

> insert into table phoenix_table select bar,foo,12.3 as fl,22.2 as dl from pokes;

成功、查詢

在phoenix中查詢

還可以使用phoenix導入數據，看官網的解釋

注意：phoenix4.8認為加tbale關鍵字為語法錯誤，其他版本沒試，不知道官網怎么沒說明

創建外部表

For external tables Hive works with an existing Phoenix table and manages only Hive metadata. Deleting an external table from Hive only deletes Hive metadata and keeps Phoenix table

首先在phoenix創建表

phoenix> create table PHOENIX_TABLE_EXT(aa varchar not null primary key,bb varchar);

再在hive中創建外部表：

create external table phoenix_table_ext_1 ( aa string, bb string ) STORED BY 'org.apache.phoenix.hive.PhoenixStorageHandler' TBLPROPERTIES ( "phoenix.table.name" = "phoenix_table_ext ", "phoenix.zookeeper.quorum" = "hadoop01", "phoenix.zookeeper.znode.parent" = "/hbase", "phoenix.zookeeper.client.port" = "2181", "phoenix.rowkeys" = "aa", "phoenix.column.mapping" = "aa:aa, bb:bb" );

創建成功，插入成功

這些選項可以設置在hive CLI

性能調優

查詢數據

可以使用HiveQL在phoenix表查詢數據。一個簡單表查詢當hive.fetch.task.conversion=more and hive.exec.parallel=true.就可以像在Phoenix CLI一樣快。

遇到的問題：

FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. org.apache.hadoop.hbase.client.Scan.isReversed()Z

最開始我用的hbase-0.96.2-hadoop2版本，不能整合，這個是需要hbase-client-0.98.21-hadoop2.jar包，更換這個jar包就解決了，但是還是會報下面的錯

FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. MetaException(message:ERROR 103 (08004): Unable to establish connection.

于是更換了hbase的版本為0.98.21的 ok了

---------

FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. java.lang.StringIndexOutOfBoundsException: String index out of range: -1

因為字段對應不一樣

create table phoenix_table_3 (a string,b int) STORED BY 'org.apache.phoenix.hive.PhoenixStorageHandler' TBLPROPERTIES ("phoenix.table.name" = "phoenix_table_3","phoenix.zookeeper.quorum" = "hadoop01","phoenix.zookeeper.znode.parent" = "/hbase","phoenix.zookeeper.client.port" = "2181","phoenix.rowkeys" = "a1","phoenix.column.mapping" = "a:a1, b:b1","phoenix.table.options" = "SALT_BUCKETS=10, DATA_BLOCK_ENCODING='DIFF'");

hive表字段與phoenix字段一樣就可以了

----------

創建成功，插入也能成功，就是hive查詢的時候報錯找不到a1列，因為phoenix是aa列

Failed with exception java.io.IOException:java.lang.RuntimeException: org.apache.phoenix.schema.ColumnNotFoundException: ERROR 504 (42703): Undefined column. columnName=A1

create external table phoenix_table_ext (a1 string,b1 string)STORED BY 'org.apache.phoenix.hive.PhoenixStorageHandler' TBLPROPERTIES ("phoenix.table.name" = "phoenix_table_ext","phoenix.zookeeper.quorum" = "hadoop01","phoenix.zookeeper.znode.parent" = "/hbase","phoenix.zookeeper.client.port" = "2181","phoenix.rowkeys" = "aa","phoenix.column.mapping" = "a1:aa, b1:bb");

解決辦法：同上hive表字段與phoenix字段一樣就可以了
