@zurk Can you please have a look |
|
@sakalouski, just to be sure I tested |

Thank You! How about the most recent spark version (2.3.2)?

@sakalouski <https://github.com/sakalouski>, just to be sure I tested srcml
preprocrepos and it works with proper spark version which is 2.2.1 (
https://github.com/src-d/jgit-spark-connector#pre-requisites) so yes, I
think the problem is in old spark. We do not test it for 1.x versions.

We don't support 2.3.x because they changed the API in a non-backward-compatible way. |

I have installed the module as suggested and run the command:
srcml preprocrepos -m 50G,50G,50G -r siva --output ./test
Where siva is the directory, containing all the siva files. The memory parameters do not change anything.
My spark is very old (1.3) - could it be the reason? Is it runnable in pyspark (the latest one)?
