Dear all,
When I tried use logstash-output-webhdfs plugin to archive logs into hdfs, I met below error occasionly(not always). Does anyone know what happened and how to fix this ?
Failed to flush outgoing items {:outgoing\_count=\>168, :exception=\>"WebHDFS::IOError", :backtrace=\>["/home/cloudera/elasticsearch/logstash/logstash/vendor/bundle/jruby/1.9/gems/webhdfs-0.8.0/lib/webhdfs/client\_v1.rb:401:in `request'", "/home/cloudera/elasticsearch/logstash/logstash/vendor/bundle/jruby/1.9/gems/webhdfs-0.8.0/lib/webhdfs/client_v1.rb:270:in`operate\_requests'", "/home/cloudera/elasticsearch/logstash/logstash/vendor/bundle/jruby/1.9/gems/webhdfs-0.8.0/lib/webhdfs/client\_v1.rb:73:in `create'", "/home/cloudera/elasticsearch/logstash/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-webhdfs-3.0.2/lib/logstash/outputs/webhdfs.rb:210:in`write\_data'", "/home/cloudera/elasticsearch/logstash/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-webhdfs-3.0.2/lib/logstash/outputs/webhdfs.rb:205:in `write_data'", "/home/cloudera/elasticsearch/logstash/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-webhdfs-3.0.2/lib/logstash/outputs/webhdfs.rb:195:in`flush'", "org/jruby/RubyHash.java:1342:in `each'", "/home/cloudera/elasticsearch/logstash/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-webhdfs-3.0.2/lib/logstash/outputs/webhdfs.rb:183:in`flush'", "/home/cloudera/elasticsearch/logstash/logstash/vendor/bundle/jruby/1.9/gems/stud-0.0.22/lib/stud/buffer.rb:219:in `buffer_flush'", "org/jruby/RubyHash.java:1342:in`each'", "/home/cloudera/elasticsearch/logstash/logstash/vendor/bundle/jruby/1.9/gems/stud-0.0.22/lib/stud/buffer.rb:216:in `buffer_flush'", "/home/cloudera/elasticsearch/logstash/logstash/vendor/bundle/jruby/1.9/gems/stud-0.0.22/lib/stud/buffer.rb:193:in`buffer\_flush'", "/home/cloudera/elasticsearch/logstash/logstash/vendor/bundle/jruby/1.9/gems/stud-0.0.22/lib/stud/buffer.rb:112:in `buffer_initialize'", "org/jruby/RubyKernel.java:1479:in`loop'", "/home/cloudera/elasticsearch/logstash/logstash/vendor/bundle/jruby/1.9/gems/stud-0.0.22/lib/stud/buffer.rb:110:in `buffer\_initialize'"], :level=\>:warn}
my configuration as follows:
webhdfs {
codec =\> json
host =\> "master"
port =\> 50070
path =\> "/user/logstash/access\_error/dt=%{log\_date}/logstash-%{+HH}.log"
user =\> "hdfs"
}

Hello @jackhe,
Is there any mention of retries in your log before the error you shared with us? From the source code, the plugin should [retry theses kinds of errors](https://github.com/logstash-plugins/logstash-output-webhdfs/blob/master/lib/logstash/outputs/webhdfs.rb#L230).

Hi @pierhugues,
Thanks a lot for your response.
No, the error I shared is the whole thing. And when it happens, It keeps coming with every event.
I didn't modify retries\_times in my conf file.
Now I am trying "retry\_times =\> 100", so far so good.
