Hi Evans,

Just discovered that snappy-devel is missing from bigtop_toolchain. Will =
open a JIRA for it.

> Is anybody bundling Hadoop with Snappy support on Bigtop? I noticed =
that =
https://github.com/apache/bigtop/blob/master/bigtop-packages/src/common/ha=
doop/do-component-build checks for the presence of /usr/lib/libsnappy.so =
or /usr/lib64/libsnappy.so and sets $BUNDLE_SNAPPY accordingly, so it =
seems that I should just need to install the snappy package, and Hadoop =
will automatically be built with Snappy support. However, when I install =
the snappy package ("sudo yum install -y snappy" on AmazonLinux =
2015.03), the library file that gets installed is =
/usr/lib64/libsnappy.so, not /usr/lib64/libsnappy.so.1, so installing =
the snappy package has no effect on the Hadoop build.
