[moji...@gmail.com]

Hi,

    i try to compile the shark-0.8 source code, and i follow the instructions

    https://github.com/amplab/shark/wiki/Building-Shark-from-Source-Code 

    but it failed. the error log is:

    xxx/shark/memstore2/buffer/UnsafeDirectByteBufferReader.scala:39: too many arguments for method copyMemory: (x$1: Long, x$2: Long, x$3: Long)Unit

[error]     Unsafe.unsafe.copyMemory(null, _offset, dst, Unsafe.BYTE_ARRAY_BASE_OFFSET, length)

     ...  ... 

    Does anyone has any idea?

Which jdk are you using to compile? You might need a newer version.

Can you try add to the beginning of sbt/sbt file the following lines, and see what gets printed?

echo $JAVA_HOME

java -version
