/home/jack/Downloads/hypertable-master_src_0.9.7.8_modify_offset-limit
[jack@localhost hypertable-master_src_0.9.7.8_modify_offset-limit]$ vim
build.xml
i have modified build.xml file just changed line 1,17,22,23 as follows:
1 <project name="hypertable" default="compile" basedir=".">
17 <property name="src.lib.distro.dir" value="${basedir}/lib/cdh4"/>
22 <property name="build.dir" value="${basedir}/build/cdh4"/>
23 <property name="build.classes" value="${build.dir}/cdh4/classe4"/>
then
[jack@localhost hypertable-master_src_0.9.7.8_modify_offset-limit]$ ant
error arised as mentioned before.
