----------------------------------
Hi Thomas,
Apologies from my side also for not completing it completely.
I saw the changes. Looks perfect to me, everything seems to be taken care of.
We no longer need
{noformat}
setCompressMessage(boolean)
{noformat}
in BSPJob as Edward had asked. The user can choose not to specify this
parameter "hama.messenger.compression.class" in site.xml in which case
{noformat} CompressableMessageManager {noformat} would return a null and no
compressor would be created.
No, snappy 0.2.0 should have been used, my mistake.
thanks, your design taught me many things.
+1 (It has been a long issue, I hope this is resolved now)

> As you know, the exchanging data between processes, is a core part of whole
> performance in Bulk Synchronous Parallel.
> In this research, we investigate BSP message data compression in the context
> of large-scale distributed message-passing systems to reduce the
> communication time of individual messages and to improve the bandwidth of the
> overall system.
