Hi,
Installed 2.8 manually (after figuring out that I needed to define the
XERCECROOT environment variable). Having read the upstream
documentation, not sure whether librecordio should be disabled - looks
useful despite the alternatives and potentialially others are using it
(but at the end of the day it is an upstream decision).
Continuing the build process but there seems to be a problem with a
couple of patches in hive-0.9.1 :-( (had to tweak zookeeper to upgrade
to 3.4.1 but notice that the same patch has already been applied to to
trunk) Will continue to investigate.
Thanks,
Graeme

Version of xerces is:
rpm -qa | grep xerces-c
xerces-c-3.0.1-20.el6.x86_64
xerces-c-devel-3.0.1-20.el6.x86_64
Is there a dependency on xereces-c 3.1 (or earlier versions)? Have
searched G but not found any solutions. Will I need to install
xerces-c 3.1 manually?

Hi Graeme,
Somehow Roman is having some issues posting to this mailing list, so
please find his reply below:
Hi Graeme!
That's a know issue with CentOS 6 and Hadoop 0.22 build. I believe the
solution
here is to manually install xerces 2.7. It would be nice to fix this
compatibility
issue in Hadoop .22 branch, but given that xerces is only required for
librecordio
(and that seems to be depricated) may be a better option would be to turn
it off completely in the Hadoop build.
Let us know what you think.
Thanks,
Roman.
