Writing data in hive warehouse directory in two separate tables using flume
I want to write data in hive warehouse directory, in two separate tables called flumemaleemployee
and flumefemaleemployee
. Last 3 records
should be inserted in the female
table and upper 3 records
should be inserted in male
table.Below is my data:
1,alok,mumbai
1,jatin,chennai
1,yogesh,kolkata
2,ragini,delhi
2,jyotsana,pune
1,valmiki,banglore
Below is my flume
conf
code:
agent.sources = tailsrc
agent.channels = mem1 mem2
agent.sinks = stdl std2
agent.sources.tailsrc.type = exec
agent.sources.tailsrc.command = tail -F /home/cloudera/Desktop/in.txt
agent.sources.tailsrc.batchSize = 1
agent.sources.tailsrc.interceptors = i1
agent.sources.tailsrc.interceptors.i1.type = regex_extractor
agent.sources.tailsrc.interceptors.il.regex = A(\d}
agent.sources.tailsrc. interceptors. M.serializers = t1
agent.sources.tailsrc. interceptors, i1.serializers.t1. name = type
agent.sources.tailsrc.selector.type = multiplexing
agent.sources.tailsrc.selector.header = type
agent.sources.tailsrc.selector.mapping.1 = mem1
agent.sources.tailsrc.selector.mapping.2 = mem2
agent.sinks.std1.type = hdfs
agent.sinks.stdl.channel = mem1
agent.sinks.stdl.batchSize = 1
agent.sinks.std1.hdfs.path = /user/hive/warehouse/aisehibanayatp.db/flumemaleemployee
agent.sinks.stdl.rolllnterval = 0
agent.sinks.stdl.hdfs.fileType = DataStream
agent.sinks.std2.type = hdfs
agent.sinks.std2.channel = mem2
agent.sinks.std2.batchSize = 1
agent.sinks.std2.hdfs.path = /user/hi ve/warehouse/aisehibanayatp.db/flumefemaleemployee
agent.sinks.std2.rolllnterval = 0
agent.sinks.std2.hdfs.fileType = DataStream
agent.channels.mem1.type = memory
agent.channels.meml.capacity = 100
agent.channels.mem2.type = memory
agent.channels.mem2.capacity = 100
agent.sources.tailsrc.channels = mem1 mem2
I am not getting any error but when I start flume
service
with below command it just stucks at something I don't know how to deal with that since I am not getting any error
flume-ng agent --name agent -conf-file /home/cloudera/Desktop/flume1.config
and it stucks at below step:
18/11/13 08:03:00 INFO instrumentation.MonitoredCounterGroup: Shutdown Metric for type: CHANNEL, name: mem2. channel.event.take.success == 0
18/11/13 08:03:00 INFO node.Application: Starting new configuration: sourceRunners: sinkRunners:std2=SinkRunner: policy:org.apache.flume.sink.DefaultSinkProcessor@17ade71c counterGroup: name:null counters: channels:mem2=org.apache.flume.channel.MemoryChannelname: mem2

18/11/13 08:03:00 INFO instrumentation.MonitoredCounterGroup: Component type: SINK, name: std2 started
So how can I achieve this ??

The problem is typos and lack of formatting and spaces and l instead of 1. I managed to fix these and it ran, I altered your regex, you can tailor that, but most of it is an accuracy issue. Use the file as follows and it works, your own HDFS and settings of course:
agent.sources = tailsrc
agent.channels = mem1 mem2
agent.sinks = std1 std2
agent.sources.tailsrc.type = exec
agent.sources.tailsrc.command = tail -F /home/cloudera/in.txt
agent.sources.tailsrc.batchSize = 1
agent.sources.tailsrc.interceptors = i1
agent.sources.tailsrc.interceptors.i1.type = regex_extractor
agent.sources.tailsrc.interceptors.i1.regex = ^.*(1|2)
agent.sources.tailsrc.interceptors.i1.serializers = t1
agent.sources.tailsrc.interceptors.i1.serializers.t1.name = type
agent.sources.tailsrc.selector.type = multiplexing
agent.sources.tailsrc.selector.header = type
agent.sources.tailsrc.selector.mapping.1 = mem1
agent.sources.tailsrc.selector.mapping.2 = mem2
agent.sinks.std1.type = hdfs
agent.sinks.std1.channel = mem1
agent.sinks.std1.batchSize = 1
agent.sinks.std1.hdfs.path = hdfs://quickstart.cloudera:8020/user/hive/warehouse/flumemaleemployee
agent.sinks.std1.rolllnterval = 0
agent.sinks.std1.hdfs.fileType = DataStream
agent.sinks.std2.type = hdfs
agent.sinks.std2.channel = mem2
agent.sinks.std2.batchSize = 1
agent.sinks.std2.hdfs.path = hdfs://quickstart.cloudera:8020/user/hive/warehouse/flumefemaleemployee
agent.sinks.std2.rolllnterval = 0
agent.sinks.std2.hdfs.fileType = DataStream
agent.channels.mem1.type = memory
agent.channels.meml.capacity = 100
agent.channels.mem2.type = memory
agent.channels.mem2.capacity = 100
agent.sources.tailsrc.channels = mem1 mem2
If I follow documentation and If I use only mandatory properties for source. Like for "exec" the only mandatory property is type and command. So will it work with these two properties also ?? Coz I haven't understood the purpose of other properties over here

Yeah it worked but it would be very helpful if you can explain me those properties in layman terms specially the regex part so that in future I can tackle such problems

Nov 14 '18 at 7:48
It ran and for me it’s over. Work to do

If I follow documentation and If I use only mandatory properties for source. Like for "exec" the only mandatory property is type and command. So will it work with these two properties also ?? Coz I haven't understood the purpose of other properties over here

Yeah it worked but it would be very helpful if you can explain me those properties in layman terms specially the regex part so that in future I can tackle such problems

Okay whenever you get time will you help me with understanding these properties ?
– RushHour
Nov 14 '18 at 7:49
Ok will do but the example is reading from a file that gets the stuff and from start of line looks for 1 or 2 ans splits to 2 files. I will post you a link to read on regex

The problem is typos and lack of formatting and spaces and l instead of 1. I managed to fix these and it ran, I altered your regex, you can tailor that, but most of it is an accuracy issue. Use the file as follows and it works, your own HDFS and settings of course:
agent.sources = tailsrc
agent.channels = mem1 mem2
agent.sinks = std1 std2
agent.sources.tailsrc.type = exec
agent.sources.tailsrc.command = tail -F /home/cloudera/in.txt
agent.sources.tailsrc.batchSize = 1
agent.sources.tailsrc.interceptors = i1
agent.sources.tailsrc.interceptors.i1.type = regex_extractor
agent.sources.tailsrc.interceptors.i1.regex = ^.*(1|2)
agent.sources.tailsrc.interceptors.i1.serializers = t1

If I follow documentation and If I use only mandatory properties for source. Like for "exec" the only mandatory property is type and command. So will it work with these two properties also ?? Coz I haven't understood the purpose of other properties over here

Not sure I understand the regex. Should it not be based on value of first col, 1 or 2?
