I am seeing the following error during handing over segments to hdfs. I have to replicas and I noticed that only one replica fails. The other is always successful. Also, this error is intermittent and does not happen always.
I looked through the open issues in github and there were similar(not exactly the same) issues reported because of a bug in hdfs-storage extension but in older versions of druid.
I am using version 0.16 incubating.
Appreciate your help and insight.
