This has gone in now. You should be able to rebase, re-source
impala-config.sh, restart the minicluster (eg. with ./buildall.sh -noclean
-notests -start_minicluster), and continue working as normal.
If you rebase and fail to re-source impala-config.sh, you may see an error
like:
Traceback (most recent call last):
File "/home/thomas/Impala/infra/python/bootstrap_virtualenv.py", line
383, in <module>
kudu_client_dir = find_kudu_client_install_dir()
File "/home/thomas/Impala/infra/python/bootstrap_virtualenv.py", line
316, in find_kudu_client_install_dir
kudu_base_dir = os.environ["IMPALA_KUDU_HOME"]
File "/usr/lib/python2.7/UserDict.py", line 40, in __getitem__
raise KeyError(key)
KeyError: 'IMPALA_KUDU_HOME'
Let me know if you encounter any other issues.
