Paulo Motta commented on CASSANDRA-10347: ----------------------------------------- bq. Isn't using mapreduce.output.bulkoutputformat.maxfailedhosts a better way to do this? Does that not work for this use case? Probably yes, but [~wanshenghua] could tell better, did you try the {{mapreduce.output.bulkoutputformat.maxfailedhosts}} property? Unfortunately I just discovered that property after implementing the new one, my bad. Anyway, I guess the parameters are not mutually exclusive, as you may want still want to blacklist nodes that are alive. Since it's already implemented and to be consistent with sstable loader, I think it's still valid to have an {{ignorehosts}} property in addition to {{maxfailedhosts}}. > Bulk Loader API could not tolerate even node failure > ---------------------------------------------------- > > Key: CASSANDRA-10347 > URL: https://issues.apache.org/jira/browse/CASSANDRA-10347 > Project: Cassandra > Issue Type: Bug > Reporter: Shenghua Wan > Assignee: Paulo Motta > Fix For: 2.1.x, 2.2.x, 3.0.x > > > When user uses CqlBulkOutputFormat, it tries to stream to all the nodes in > the token range, which includes the dead nodes.
