A patch for the same JIRA intended to be applied to the llap branch-1 branch would be named HIVE-9999.branch-llap1.patch
".
The following git command creates a patch:
...
- Don't make any changes to
hive_metastore.thrift
until instructed below. - Use the approved version of Thrift. This is currently
thrift-0.9.3
, which you can obtain from http://thrift.apache.org/. - Build the Thrift compiler from its sources, then install it:
cd /path/to/thrift-0.9.3
./configure --without-csharp --without-ruby
make
sudo make install
- Before proceeding, verify that
which thrift
returns the build of Thrift you just installed (typically/usr/local/bin
on Linux); if not, edit your PATH and repeat the verification. Also verify that the command 'thrift -version' returns the expected version number of Thrift. - Now you can run the Maven 'thriftif' profile to generate the Thrift code:
cd /path/to/hive-trunk/
mvn clean install -Pthriftif -DskipTests -Dthrift.home=/usr/local -Phadoop-2
- If you see an error about fb303.thrift not being found, copy it to the appropriate directory and run above command again. On centOS/RHEL:
cp /path/to/thrift-0.9.3/contrib/fb303/if/fb303.thrift /usr/local/share/fb303/if/fb303.thrift
- Use
svn status
to verify that the code generation was a no-op, which should be the case if you have the correct Thrift version and everyone has been following these instructions. If you can't figure out what is going wrong, ask for help from a committer. - Now make your changes to
hive_metastore.thrift
, and then run the compiler again, from /path/to/hive-trunk/<hive_metastore.thrift's module>:mvn clean install -Pthriftif -DskipTests -Dthrift.home=/usr/local -Phadoop-2
- Now use
svn status
andsvn diff
to verify that the regenerated code corresponds only to the changes you made tohive_metastore.thrift
. You may also needsvn add
if new files were generated (andsvn remove
if files have been obsoleted). cd /path/to/hive-trunk
ant clean package
- Verify that Hive is still working correctly with both embedded and remote metastore configurations.
