Yazan Boshmaf commented on GIRAPH-676:
--------------------------------------
Armando, these all are great remarks. Thanks!
Extending this guide to cover different Hadoop releases should be very useful.
As for the pseudo-distributed mode, one need to update "mapred-site.xml" so
that at least 4 mappers can be run at once (and thus the unittests won't fail).
This is because Giraph’s code assumes that you can run at least 4 mappers at
once, but unfortunately the default configuration allows only 2. Adding a
section that explains this will be useful as well (in fact, in this two-node
distributed mode, if the second datanode goes down, the cluster will work in
pseudo-distributed mode but will end up with runtime exceptions because of the
default value concerning number of mappers! So, we do need to update the
current description to take this case into consideration).
Avery, any comments on this patch? IMHO, the current content is very helpful
and we can iteratively improve/extend it over time. What do you think?
