Actually we discussed this on the Nutch mailing list, and the overall

0.12 still looks too fresh. Do you think we should revisit this issue?
I think the experience on big clusters at Yahoo! is that 0.12.1 should
be more stable than 0.11.2, but others can confirm that.
Hm.. That's not the impression I have from JIRA and the mailing list. My
impression is that even though 0.12.1 is more robust in some situations,
the significant changes (checksum filesystem, speculative execution, in
memory sorting, improved map output handling, etc, etc) made between
these releases introduced many subtle bugs which only now start coming
into light.
At the same time, I've had relatively positive experience with 0.11.2 on
moderately sized clusters (dozen machines). That's why I proposed that
Nutch should use 0.11.2 for the upcoming release.
