[jira] [Updated] (FLUME-1379) source's type is avro and sink's
type is hdfs but sink don't to work
[ https://issues.apache.org/jira/browse/FLUME-1379?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
jack li updated FLUME-1379:
---------------------------
Description:
hello everyone!
1, source's type is exec and sink's type is hdfs .the event can write to the hdfs.But when I change the source's type is avro ,and no change sink's type,no event write to hdfs.
2, flume.conf
#List sources, sinks and channels in the agent
weblog-agent.sources = tail
weblog-agent.sinks = avro-forward-sink01
weblog-agent.channels = jdbc-channel01
#webblog-agent sources config
weblog-agent.sources.tail.type = avro
weblog-agent.sources.tail.port = 41414
weblog-agent.sources.tail.bind = 0.0.0.0
#avro sink properties

weblog-agent.sinks.avro-forward-sink01.type = hdfs
weblog-agent.sinks.avro-forward-sink01.hdfs.path = hdfs://hadoop-01:8020/flume/web
weblog-agent.sinks.avro-forward-sink01.hdfs.rollInterval = 120
