Hi. I've been looking for a client-side solution for fault injection in HDFS. We had a naturally unstable HDFS cluster that helped uncover a lot of issues in HBase; now that it has been stabilized, we miss it already :) To keep testing without actually disrupting others' use of HDFS or having to deploy a new version, I was thinking about having a client-side schema (e.g. fhdfs) map to a wrapper over the standard DFS that would inject failures and delays according to some configs, similar to https://hadoop.apache.org/docs/r2.7.2/hadoop-project-dist/hadoop-hdfs/FaultInjectFramework.html However I wonder if something like this exists already? --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@hadoop.apache.org For additional commands, e-mail: user-h...@hadoop.apache.org
