flume-ng Unable to put batch on required channel error
hello,
I saw lot's of flume-ng 1.3.1 agent Exception said Unable to put batch on
required channel,and then disconnected.
what is the effect? lost data or duplicate data?
What caused this error?
How to avoid this error?
some of my conf:
agent46.channels.memch1.type = memory
agent46.channels.memch1.capacity = 100000
agent46.channels.memch1.transactionCapactiy = 1000
agent46.sources.userlogsrc.type = avro
agent46.sinks.myhdfssink.type = hdfs

Posted by 周梦想 <ab...@gmail.com>.
thank you. I once increased hdfs batch size more than 1000, but it report
the ChannelException more frequence. so I changed small and small, batch
size to 50 is less error.

Re: flume-ng Unable to put batch on required channel error
Posted by Hari Shreedharan <hs...@cloudera.com>.
Try increasing the callTimeout for HDFS Sink - that is in milliseconds. Also, you should try using a batch size/txnEvent max of at least 100 (or more). Using more HDFS sinks will also improve performance by increased parallel writes since each sink is single threaded and writes to only one file at a time. (note that each HDFS Sink should write to a different directory).

Re: flume-ng Unable to put batch on required channel error
Posted by 周梦想 <ab...@gmail.com>.
Hello,
I wrote a test java file to put local files to hdfs, it put 1.1GB files to
hdfs spent about 35 seconds. while using flume, 100MB files it should spend
about 3-5 minutes.
why flume is so slow and always report error? how to enlarge the flume hdfs
sink throughput?
