Do you mean hadoop-2.4 or 2.6? not sure if this is the issue but I'm also compiling the 1.5.1 version with scala 2.11 and hadoop 2.6 and it works.

The command I use is: dev/change-version-to-2.11.sh<http://change-version-to-2.11.sh> build/sbt -Pyarn -Phadoop-2.11 -Dscala-2.11 followed by compile in the sbt shell. The error I get specifically is: spark/core/src/main/scala/org/apache/spark/rpc/netty/NettyRpcEnv.scala:308: no valid targets for annotation on value conf - it is discarded unused. You may specify targets with meta-annotations, e.g. @(transient @param) [error] private[netty] class NettyRpcEndpointRef(@transient conf: SparkConf) [error] However I am also getting a large amount of deprecation warnings, making me wonder if I am supplying some incompatible/unsupported options to sbt. I am using Java 1.8 and the latest Spark master sources. Does someone know if I am doing anything wrong or is the sbt build broken? thanks for you help, --Jakob
