Flume MaxCompute Sink插件__數據入雲_數據集成-阿裏雲

Apache Flume是一個分布式的、可靠的、可用的係統，可用於從不同的數據源中高效地收集、聚合和移動海量日誌數據到集中式數據存儲係統。

ODPS Sink是基於ODPS DataHub Service開發的Flume插件，可以將Flume的Event數據導入到ODPS中。插件兼容Flume的原有功能特性，支持ODPS表自定義分區、且可以自動創建分區。

二、環境要求

1、JDK(1.6以上，推薦1.7)

2、Flume-NG 1.x

三、插件部署

1、下載ODPS Sink插件並解壓：aliyun-odps-flume-plugin

2、部署ODPS Sink插件：將文件夾odps_sink移動到Apache Flume安裝目錄下：

$ mkdir {YOUR_APACHE_FLUME_DIR}/plugins.d
$mv  odps_sink/  { YOUR_APACHE_FLUME_DIR }/plugins.d/

移動後，核驗ODPS Sink插件是否已經在相應目錄：

$ ls { YOUR_APACHE_FLUME_DIR}/plugins.d
odps_sink

部署完成後，隻需要在Flume的配置文件中將sink的type字段配置為:

com.aliyun.odps.flume.sink.OdpsSink

即可使用

四、配置示例

例：將日誌文件中的結構化數據進行解析，並上傳到ODPS表中

需要上傳的日誌文件格式如下（每行為一條記錄，字段之間逗號分隔）:

#test_basic.log
some,log,line1
some,log,line2
...

第一步、在ODPS 的 project創建ODPS Datahub表

建表語句如下所示：

CREATE TABLE hub_table_basic (col1 STRING, col2 STRING) 
    PARTITIONED BY (pt STRING)
    INTO 1 SHARDS
    HUBLIFECYCLE 1;

第二步、創建Flume作業配置文件：

在Flume安裝目錄的conf/文件夾下創建名為odps_basic.conf的文件，並輸入內容如下：

# odps_basic.conf
# A single-node Flume configuration for ODPS
# Name the components on this agent
a1.sources = r1
a1.sinks = k1
a1.channels = c1
# Describe/configure the source
a1.sources.r1.type = exec
a1.sources.r1.command = cat {YOUR_LOG_DIRECTORY}/test_basic.log
# Describe the sink
a1.sinks.k1.type = com.aliyun.odps.flume.sink.OdpsSink
a1.sinks.k1.accessID = {YOUR_ALIYUN_ODPS_ACCESS_ID}
a1.sinks.k1.accessKey = {YOUR_ALIYUN_ODPS_ACCESS_KEY}
a1.sinks.k1.odps.endPoint = https://service.odps.aliyun.com/api
a1.sinks.k1.odps.datahub.endPoint = https://dh.odps.aliyun.com
a1.sinks.k1.odps.project =  {YOUR_ALIYUN_ODPS_PROJECT}
a1.sinks.k1.odps.table = hub_table_basic
a1.sinks.k1.odps.partition = 20150814
a1.sinks.k1.batchSize = 100
a1.sinks.k1.serializer = DELIMITED
a1.sinks.k1.serializer.delimiter = ,
a1.sinks.k1.serializer.fieldnames = col1,,col2
a1.sinks.k1.serializer.charset = UTF-8
a1.sinks.k1.shard.number = 1
a1.sinks.k1.shard.maxTimeOut = 60
a1.sinks.k1.autoCreatePartition = true
# Use a channel which buffers events in memory
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 1000
# Bind the source and sink to the channel
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1

$ cd { YOUR_APACHE_FLUME_DIR}
$ bin/flume-ng agent -n a1 -c conf -f conf/odps_basic.conf -Dflume.root.logger=INFO,console

...
Write success. Event count: 2
