我的twitter数据格式不可读。我使用flume获取twitter数据，我正在尝试使用配置单元表读取这些数据。但我在hdfs中看不到正确的数据。详情如下：
Flume-env.sh-

export JAVA_HOME=/usr/java/jdk1.7.0_67-cloudera
FLUME_CLASSPATH="/opt/cloudera/parcels/CDH-5.8.0-1.cdh5.8.0.p0.42/lib/flume-ng/lib/flume-sources-1.0-SNAPSHOT.jar

twitter.conf-

TwitterAgent.sources = Twitter
    TwitterAgent.channels = MemChannel
    TwitterAgent.sinks = HDFS

    TwitterAgent.sources.Twitter.type=org.apache.flume.source.twitter.TwitterSource
    TwitterAgent.sources.Twitter.channels = MemChannel
    TwitterAgent.sources.Twitter.consumerKey = xxxxxxxxxxxxxxxxxxxxxxxxx
    TwitterAgent.sources.Twitter.consumerSecret = xxxxxxxxxxxxxxxxxxxxxxxx
    TwitterAgent.sources.Twitter.accessToken = xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
    TwitterAgent.sources.Twitter.accessTokenSecret = xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

    TwitterAgent.sources.Twitter.keywords = hadoop, bigdata, data science

    TwitterAgent.sinks.HDFS.channel = MemChannel
    TwitterAgent.sinks.HDFS.type = hdfs
    TwitterAgent.sinks.HDFS.hdfs.path = hdfs://opt:8020/user/flume/tweets
    TwitterAgent.sinks.HDFS.hdfs.fileType = DataStream
    TwitterAgent.sinks.HDFS.hdfs.writeFormat = Text
    TwitterAgent.sinks.HDFS.hdfs.batchSize = 100
    TwitterAgent.sinks.HDFS.hdfs.rollSize = 0
    TwitterAgent.sinks.HDFS.hdfs.rollCount = 100

    TwitterAgent.channels.MemChannel.type = memory
    TwitterAgent.channels.MemChannel.capacity = 100
    TwitterAgent.channels.MemChannel.transactionCapacity = 100

当我少做一个文件时：

有人能告诉我哪里出了问题吗？我需要这个数据的可读格式的配置单元表。
