[druid-user] error saving segment in hdfs

Hey Nicu,

You may be hitting this issue: https://github.com/druid-io/druid/issues/1813 which should be better in 0.8.2 due to this patch: https://github.com/druid-io/druid/pull/1721.

You could try 0.8.2-rc1 to see if it works for you, or you could do the workaround of putting all of your Hadoop jars on the Druid classpath.
