Hi All,
I am trying to setup the hadoop in Highly available mode. So i download
the source cocde from
https://github.com/facebook/hadoop-20-warehouse/tree/master/src. When I try to
make the build of these source code i got the following error. Why this happen
? If anyone face this same one in your configuration , Please told how can you
handle and rectify this error .
