四（2）、flume遇到的问题

使用的是6.0.1cdh上面的1.8版本的flume：
从mysql抽取数据到hdfs
flume-ng agent --conf conf --conf-file conf/flume-conf04.properties --name a1 -Dflume.root.logger=INFO,console

a1.channels.ch1.type = memory
a1.sources.sql-source.channels = ch1
a1.channels = ch1
a1.sinks = HDFS
a1.sources = sql-source

a1.sources.sql-source.type = org.keedio.flume.source.SQLSource

a1.sources.sql-source.connection.url = jdbc:mysql://ip地址:3306/库名
a1.sources.sql-source.user = 用户名
a1.sources.sql-source.password = 密码
a1.sources.sql-source.table = 表名
a1.sources.sql-source.columns.to.select = *

a1.sources.sql-source.incremental.column.name = id
a1.sources.sql-source.incremental.value = 0

a1.sources.sql-source.run.query.delay=5000

a1.sources.sql-source.status.file.path = /var/lib/flume-ng/flume
a1.sources.sql-source.status.file.name = sql-source.status

a1.sinks.HDFS.channel = ch1
a1.sinks.HDFS.type = hdfs
a1.sinks.HDFS.hdfs.path = hdfs://node01/user/hive/warehouse/test.db/dim_period_d
a1.sinks.HDFS.hdfs.fileType = DataStream
a1.sinks.HDFS.hdfs.writeFormat = Text
a1.sinks.HDFS.hdfs.rollSize = 268435456
a1.sinks.HDFS.hdfs.rollInterval = 0
a1.sinks.HDFS.hdfs.rollCount = 0
