Wrong file format

I am working in Cloudera and have just started to learn it. So I have been trying to implement a famous twitter example with flume. With efforts, I have been able to stream the data from Twitter and now it is being saved in a file. After I have got the data now I want to perform analysis on Twitter data. But the issue is I cannot get the twitter data in the table. I have successfully created the "tweets" table but cannot load the data in the table. Below I have given Twitter.conf file, external table creation query, data load query, error message and some chunk of the data I have got. Kindly guide me where I am doing wrong. Please note I have been writing the queries in HIVE editor.

 

Twitter.conf file

# Naming the components on the current agent. 
TwitterAgent.sources = Twitter 
TwitterAgent.channels = MemChannel 
TwitterAgent.sinks = HDFS

# Describing/Configuring the source 
TwitterAgent.sources.Twitter.type = org.apache.flume.source.twitter.TwitterSource
TwitterAgent.sources.Twitter.consumerKey = 95y0IPClnNPUTJ1AHSfvBLWes
TwitterAgent.sources.Twitter.consumerSecret = UmlNcFwiBIQIvuHF9J3M3xUv6UmJlQI3RZWT8ybF2KaKcDcAw5
TwitterAgent.sources.Twitter.accessToken = 994845066882699264-Yk0DNFQ4VJec9AaCQ7QTBlHldK5BSK1 
TwitterAgent.sources.Twitter.accessTokenSecret =  q1Am5G3QW4Ic7VBx6qJg0Iv7QXfk0rlDSrJi1qDjmY3mW
TwitterAgent.sources.Twitter.keywords = hadoop, big data, analytics, bigdata, cloudera, data science, data scientiest, business intelligence, mapreduce, data warehouse, data warehousing, mahout, hbase, nosql, newsql, businessintelligence, cloudcomputing



# Describing/Configuring the channel 
TwitterAgent.channels.MemChannel.type = memory 
TwitterAgent.channels.MemChannel.capacity = 10000 
TwitterAgent.channels.MemChannel.transactionCapacity = 100

# Binding the source and sink to the channel 
TwitterAgent.sources.Twitter.channels = MemChannel
TwitterAgent.sinks.HDFS.channel = MemChannel 

# Describing/Configuring the sink 

TwitterAgent.sinks.HDFS.type = hdfs 
TwitterAgent.sinks.HDFS.hdfs.path = /user/cloudera/latestdata/
TwitterAgent.sinks.flumeHDFS.hdfs.fileType = DataStream 
TwitterAgent.sinks.HDFS.hdfs.writeFormat = Text 
TwitterAgent.sinks.HDFS.hdfs.batchSize = 1000
TwitterAgent.sinks.HDFS.hdfs.rollSize = 0 
TwitterAgent.sinks.HDFS.hdfs.rollCount = 10000 

External table query and load data in table query

 

CREATE External  TABLE tweets (


id BIGINT,
   created_at STRING,
   source STRING,
   favorited BOOLEAN,
   retweet_count INT,
   retweeted_status STRUCT<

   in_reply_to_screen_name STRING
 ) 
 PARTITIONED BY (datehour INT)

LOAD DATA INPATH '/user/cloudera/latestdata/FlumeData.1540555155464'
INTO TABLE `default.tweets`
PARTITION (datehour='2013022516')

Error When I try to load data into the table

 

Error while processing statement: FAILED: Execution Error, return code 20013 from org.apache.hadoop.hive.ql.exec.MoveTask. Wrong file format. Please check the file's format.

Re: Wrong file format

Hi,

 

Flume's HDFSEventSink writes to a SequenceFile by default. The name of your HDFS sink is wrong in your Flume configuration. Please change it to this: 

 

TwitterAgent.sinks.HDFS.hdfs.fileType = DataStream 

 

Here is the documentation:


https://flume.apache.org/FlumeUserGuide.html#hdfs-sink

 

Best regards,

Re: Wrong file format

Gabor now the data is loaded into the table but when I execute a query it gives this error
