Subject Automatic collector fall over
Date Fri, 07 Oct 2011 00:06:44 GMT
Hey flume expert,

First off I wanted to thank everybody for all the help so far. I managed to
get flume working consistantly across many nodes. Today I tried to update to
Automatic Fallover chains and I seem to have run into a bunch of issues.
Namely both the source node and collector nodes are throwing errors.

The source nodes are saying that they are configured without a collector.
{ ackedWriteAhead => { stubbornAppend => { insistentOpen => fail( "no
collectors" ) } } }

and the collector nodes are throwing this error in the log files.

The config that I am using is
beacon_beacon02use : rpcSource(12345) | autoE2EChain ;
beacon_beacon03use : rpcSource(12345) | autoE2EChain ;
beacon_beacon04use : rpcSource(12345) | autoE2EChain ;
beacon_flume01use : collectorSource(35853) |
collectorSink("hdfs://private/user/flume/%Y/beaconlog","syslog" , 30000);


Thanks in advance for your help,
Jonathan
