Hit a Scala compiler bug when building Spark API docs. To reproduce this bug, checkout Spark latest master (452690ba1cc3c667bdd9f3022c43c9a10267880b) and run "build/sbt mllib/doc" with JDK 7 (1.7.0_79), Scala 2.10.5, and Mac OS X). I don't have a minimal example code to reproduce this, but this doesn't happen with JDK 8. However, it is not a workaround for us because we need to prepare releases using JDK 7. I checked similar Scala JIRAs but I believe that this is a different bug. See SPARK-12000 for more discussions.

Error message:

[error] no-symbol does not have an owner

Here's the faulty comment in Spark:

% git grep -E 'computeCost.RDD'
mllib/src/main/scala/org/apache/spark/mllib/clustering/BisectingKMeansModel.scala:   * Java-friendly version of [[computeCost(RDD[Vector])*]].

Xiangrui Meng (mengxr) said (edited on Dec 3, 2015 6:35:17 AM UTC):
Thanks for explaining the cause! This was fixed in Spark. Should we fix this in Scala 2.10.x to avoid future errors? This is quite hard for me to debug.

Btw, could you explain more about how you trace down the root cause?

I attached a debugger to the SBT process with a breakpoint at raising of the fatal error, and looked up the stack to see what was happening at the time.

We're don't have a plan for a further 2.10 release, other than if for high severity bugs is found. We would accept a patch against the 2.10.x branch for this bug, though, and the fix would be part of 2.10.7 if we ended up releasing it.

@retronym said:
Also: It is sort of an accident that this doesn't crash anymore on 2.11+, so the bug fix to make Scaladoc more robust would be welcome there too.
