Master compilation

I am synced with apache/spark master but getting error in spark/sql compilation... Is the master broken ? [info] Compiling 34 Scala sources to /home/debasish/spark_deploy/sql/core/target/scala-2.10/classes... [error] /home/debasish/spark_deploy/sql/core/src/main/scala/org/apache/spark/sql/parquet

That method was added in Java 7. The project is on Java 6, so I think this was just an inadvertent error in a recent PR (it was the 'Spark parquet improvements' one). I'll open a hot-fix PR after looking for other stuff like this that might have snuck in. -- Sean Owen | Director, Data Science | Lo

Will do. I'm just finishing a recompile to check for anything else like this. The reason is because the tests run with Java 7 (like lots of us do including me) so it used the Java 7 classpath and found the class. It's possible to use Java 7 with the Java 6 -bootclasspath. Or just use Java 6. -- Se

ephemeral storage level in spark ?

2014-04-05 Thread Mridul Muralidharan
Hi, We have a requirement to use a (potential) ephemeral storage, which is not within the VM, which is strongly tied to a worker node. So source of truth for a block would still be within spark; but to actually do computation, we would need to copy data to external device (where it might lie aro

Hi Mridul, Do you mean the scenario that different Spark applications need to read the same raw data, which is stored in a remote cluster or machines. And the goal is to load the remote raw data only once? Haoyuan On Sat, Apr 5, 2014 at 4:30 PM, Mridul Muralidharan wrote: > Hi, > > We have a
