Subject Re: Jenkins build became unstable: gora-trunk » Apache Gora :: Hbase #206
Date Sun, 08 Apr 2012 16:04:58 GMT
Hi Lewis,

Thanks for updating. The HBase (mapreduce) tests are very sensitive to
minor deviations from standard network configuration. For example I also
noticed that having a wrong hosts file entry can make the mini cluster
instances bind to different interfaces therefore unable to connect in
certain cases.

Anyway, it's good to keep this in mind.
