Make an rdd out of elems, write it to disk, verify the written partitions' sizes match fileSizes, read it
back in, verify the contents are the same.
Make an rdd out of elems, write it to disk, verify the written partitions' sizes match fileSizes, read it
back in, verify the contents are the same.
if one integer is provided here, assume 4 partitions with that size. If two are provided, assume
4 partitions where the first's size matches the first integer, and the remaining three match the
second. Otherwise, the partitions' sizes and number must match fileSizes.
The parameterless execute method has been deprecated and will be removed in a future version of ScalaTest. Please invoke execute with empty parens instead: execute().
The trap method is no longer needed for demos in the REPL, which now abreviates stack traces, and will be removed in a future version of ScalaTest
Base-trait for tests that check round-trip correctness and on-disk sizes for a given RDD-serde implementation.
